Please fix protect

[Seraphor]

being forced to press the button more often is not really a fix.

But it will feel like you're actually doing something with it, it'll be more satisfying to use.
That's the idea around every single skill in the game.
You could boil all healers down to one mitigation skill with a 30m duration, one HoT with a 30m duration and a GCD heal and it would all work out fine and balanced, but it wouldn't be interesting or satisfying to play.

On Shell/Protect mutual exclusivity and damage types: You're right, if these were still role skills.

But I think if they were a WHM only mechanic, they wouldn't be seen as strictly mandatory (because AST doesn't always get the Bole out and SCH doesn't always get a Critlo) so it would simply be a weaving skill used as a bonus, and would make WHM more interesting to play.
