Everyone having access to 25 stacks of might SOLO, in addition to other damage increasing boons (fury, quickness, too a extent alacrity) is the reason for the power creep. Ever wonder why P/P can kill you in a second? They usually have almost 25 stacks of might, fury etc. Ever wonder why Mesmer is so strong while having a paladin amulet? 25 stacks of might and high durations of every other boon. Why is holosmith so strong? 25 stacks of might and nearly every other boon.
It needs to be changed. There should be no way that one character solo should be able to have access to 25 stacks of might and high up time of other boons. 25 stacks of might should be reserved for team synergy, not one character. I believe if Anet either changed how much power/condi might offers in pvp or significantly lower how much access a single profession has of might and other boons. Then we will see a significant decrease in bursty damage all around.
Nearly every class has access to almost every boon in high duration or intensity at all times. When you journey back to the beginning of the game, it was not like this. A skill like staff #4 on guardian was considered good because it provided the team with so much might at once. Because might wasn't in abundance nor were any other boons really. Not anymore.
Ben, Anet, you guys need to seriously re-examine how much and how often a single class has access to boons. Particularly the damage increasing ones.
