Its completely fair. Every class doesn't have to be affected exactly the same with every ability, its true for abilities already in the game. A Sorc being useless for 4 secs is the point of interrupting them. You punish and reward players for using and not avoiding interrupts. I said tech/force abilities because idk if the devs are sophisticated enough with coding to only have it affect healing abilities but i would also recommend going that route. As for HoTs, well thats the point... they heal over time interrupts shouldn't affect them.
I agree about the faster pace but thats only due to scaling and stat issues. Add a healer to the equation and the pace halts dramatically add a Tank and it comes to an immediate halt. A interrupt should be a deciding factor on whether the heal gets out or not and the effectiveness of that healer for the next 4 secs, I have no problem having it affect the resolve bar and naturally you would be immune if your bar was maxed out.
The coordinated burst statement is spot on. Teams and players should be rewarded for this type of coordination and counterplay.
I never said Guard was not important, I said it was lazy by design and rewards sloppy play because its a passive mitigation that due to the current state of the game can be almost an impenetrable and uncounterable style of play. Each class has there own abilities that prevent them from getting globaled, ontop of proper positioning, awareness of surroundings and the flow of battle. Guard is too passive and lazy to warrant how powerful the ability is.
The game rewards the trinity far more than it should. Meaning any group of players lacking a piece of the trinity ie, tank,healer combo is at a huuuuge disadvantage to the opposing team.
A tank/dps combo is good, a healer/dps combo is good. But the amount of synergy that goes with a tank/healer combo is leaps and bounds far more impactful on the battlefield than either of those two other combo.
I do know that nerfing one class or one ability can affect every class either positively or negatively but something has to be done.
