It's possible that I might have to do it at some point in the future for one reason or another, but at the very least doing it for combination strike doesn't feel worth it right now. If that changes in the future then we might be able to do something.

Needs more details, testing method, etc.

If you notice, when you use skills that perform basic attacks and do damage, it doesn't actually say the name of the skill next to the damage instance. That's part of why it's difficult - all the basic attack skills would have to get new flags added.

It's not as easy as just making it work with basic attack skills, unfortunately, so it's unlikely.

Generally it is something both parties should have a say in, like Raigen says, IMO. This isn't an official statement or ruling, just my opinion.

It shouldn't break your airborne status anymore.

Does Death Knighting really need a buff?

It won't work with basic attack skills, no. Those do not have a Power/SWA to boost; they just cause you to basic attack.

Checkmate's 3 round CD might be a relic of an older time, but it exists because it's just straight up better than basic attacking. It could be adjusted though.

Alright, here you go. Post anything you want added in submissions. If you have any questions, let me know.
