Now that that's out, you might wanna move fast; Cryptic practically invented the concept of changing a raid to defeat widely-publicized methods of winning. They used to change Hamidon every few months to shake up raid strategy.
If everybody is avoiding those lines, Gozer will move them, or change the trigger.
That, was why I gave up on Hamidon. The rewards, while good, wasn't enough to make up for the frustration of figuring out the encounter again and again and again. Then again, I don't play Cryptic games for raid encounters, I had EverQuest for that. No, I play Cryptic games because of the stories they can tell. CoH, CoV, CO all had pretty interesting stories, but sadly the stories in STO are just not up to par with what Cryptic has done in other games.
