Earthbound Vengeance saps your momentum whenever you hit a resistance to it, despite being bonus damage now.

So! I've been playing Druid/Priest for a while now and while plants aren't as awful as people make them out to be, they're definitely a more-than-invoke-level momentum investment for their payoff which can.. kinda vary (11M to mass > BB > invig, mass > quickness is ROUGH and I would NOT be doing it if not for wildshape/animal bennies). 
Sometimes it's really good! Sometimes the enemy mobs get yote out of their range every round because of your allies and that momentum does NOTHING. Sometimes your opponent smartly refuses to stand in the splash zone and it also does nothing.

But.. that's if the plants LET you buff them in the first place.

The way that Druidic Tending prioritizes plants is currently a little arcane. I'd briefly been led to believe that it prioritized earlier-placed plants over later-placed ones, but after dropping massed nature's bounty and then trying to quickness buff my previously-placed burning bushes I realised it's actually just a madhouse and there's no clear pattern to it.
Worse, spawning devil vines at ANY point means you can't buff anything, because it's gonna get eaten. Drop nature's bounty and wanna invig it in a crowd of devil vines from 3 turns ago? lol, lmao.

This isn't really workable for any kind of strategy.

So! Solutions!

A) Uncap it. Just let me buff my plants indiscriminately. It'd actually be pretty nice to be able to get my choice of two plant types out round 1 and then buff them ALL round 2, even IF there's devil vines in their number. I'd kind of just prefer this the most.
B) If not that, put Devil Vines on the rock-bottom of druidic tending's priority at LEAST. Skip over them and have a whole separate check for them if you gotta. I should not have to see red lines on my devil vines instead of literally anything else. Nobody is using vines for the damage I'm 1-pointing them next time I restat.
C) Give it some logical prioritizing? Something you can plan around. Oldest plants, newest plants, closest plants, already-buffed plants, whatever. Also! Prioritize the caster's plants first, PLEASE. I don't mind helping other druids out but I got my own strategies over here, too.
D) Admittedly, if we aren't gonna get uncapped tending it'd be nice to have the cap be 1 + buff rank so you can catch four plants without spirits. Spirits are a MASSIVE cost for that.

(Edit: Also, it's just occurred to me to mention this, but it's been brought up a few times before that DT is kind of a weird thing to be MC-only and stifles subclass plant druid gameplay. I think if you were going to uncap it you could realistically have the uncapped version be MC/Inno only, with it behaving like it is now when subclassed. But that naturally wants the priority changes to come with it.
No comment on if anything else should get MC'd instead, this isn't the thread for it.)

The 'Memory Shards' button in the sidebar isn't added to the sidebar when it's first unlocked (talking to Nemalyth for the first time, IIRC?).

Fortunately, it shows up after a relog so this only causes a bit of confusion.

Plant Druid isn't bringing home any awards compared to it's summoning and basic attacking components, it does have a decently solid gameplay loop of just applying your growth inducing skills over and over but I have a good thematic suggestion for an item that isn't typically used very often.

Sometimes you just need to get a plant out immediately, Druid should have an option for this, I suggest Miracle Fertilizer fully grows a plant immediately (something like it applies growth 10 or something), the downside of this is the range is limited to your normal throwing range, and you can only equip so many of them on your belt.

Why not have this option for if you really desperately need a Listblume or Burning Brush immediately? I think its a solid idea.

On a Leash is considered a cleansable negative status effect. So your performer/Dark bard allies will.. very often cleanse On A Leash off of you when using Cantus.

Unsure if a bug, but considering On a Leash (from an ally) is generally a good beneficial status effect...

These 'mines' cannot be Aero Shifted or Terra Striked to be destroyed.

What the hell are they classified as, because I can Terra Strike a god damn **SETTING SUN**. But not a wittle WIND MINE?

I have Spark Drive and Thunder Drive, when I crit an enemy with safety on I will get Spark Drive's effect (Charge Shot) but if I get another crit while Safety is on Thunder Drive doesn't occur and I don't receive Overcharge.

Uhm, ackshually, it's Firearms* not Fiearms.

The Annorum effect of Thunderbolt does sound based damage, but still scales off of your Lightning attack.

It doesn't really SAY anywhere that it scales off of your sound attack, but Wolf's Howl also doesn't say it scales off of your sound attack so.

I figured I'd just ask.

The 'Evolving' enchant will only ever activate once per battle even if you wield two different weapons with the same enchantment.

While I do read that the 10% experience bonus doesn't stack, and that the effect will ever activate once per battle, I would assume that the 'once per battle' simply means 'on this weapon'.  This could simply be me wanting it to be the case, rather than it ever being intended to be used while dual wielding, but...

Given how neat (and rare) of an enchantment Evolving is in the first place, having two on hand to dual-wield, but only ever being able to activate one is rather unfortunate.

You effectively have to either pick which one gets the boost, or simply leave it to the whims of fate.

...Oh right. One final note and something that (as far as I know) really only impacts the test server:

Testing Evolving can be unusually difficult sometimes.

If you choose to end a battle via command, evolving will no longer proc during subsequent battles until you relog or end another battle properly, I've noticed.
Slightly inconvenient, but it is what it is..? I don't think that'll come up during normal gameplay at all, but I will point it out just in case.
