I disagree and think cel is fine as it is. All this math really points out is that cel and evade based passives are good at doing their job when you prioritize them. Now let's look at your first example and see what happens when you do that.
56% str
21% wil
12% def
27% res
37% vit

Those growths scream "All I can do is heaven kick > rapid kick and hope they die because I'm made of glass". It's a one-trick pony build that doesn't have much else to fall back on if it gets countered, much like a gunner that only does attack > parting shot. It's high risk high reward.
And that's generally what happens when you prioritize on a specific skill. RNG aside, If you try to maximize something you leave yourself lacking in other areas and when you try to cover for them you miss out a bit on the skill you were trying to max.

Now let's ignore the base classes for a second and look at promo classes that have a reasonable way of 100% hitting cel users.
Evoker
Lantern Bearer
Grand Summoner
Verglas
Engineer
Void Assassin
Black Knight
Monk
Kensei if they aren't just using it for the passives

That's 9 out of 13 and the only thing protecting you against them is 12% def, 27% res, and 37% vit, especially considering you have an 18 mod in cel which means you're also missing out on some defensive itemization.
So facing someone who has no response to a dodge build because they're centered on attacking normally isn't absurd, it means they're inflexible. There's nothing keeping a MG from subbing as an Engi and using the flamethrower, especially because upgrade is just as good of a damage boost as Absolute Death is or Elemental Augment for guns so it's not like they're missing out if they do sub Engi.
