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.
He won't. As with the rest of the Cryptic staff, he has a very busy schedule (what with Cryptic being understaffed and all).
So even if he wanted to change it, he probably won't be able to anytime soon.
The map has been out for quite a while, without any changes. Cryptic knows we know the trigger lines. At least PWE_Bran_Flakes does, as he runs STFs with us during his spare time.
