That’s a fair point, if they completely removed the regen from holy Shelton (as an example) or removed tank mastery it wouldn’t really affect how you play a tank (you will still press holy Shelton for a buster) but it will alter the role warping capability of the secondary effects stapled to these actions (or in the case of tank mastery affect the warping nature of the fact that an attack has to pierce spreadlo and kill a DPS twice over to do more than half a tanks HP)
If certain abilities were cut out specifically so it wouldn’t change how the class plays on a second to second basis would people still oppose that? Because that position is a lot harder to defend
