wich i realy hope they revert in time.
coils is a very good dungeon rewarding movement and brains over gear/aa's.
its very nice endgame content wich already many people ingame struggle to clear, despite inguild groups usualy very sucessfull.
i find it hard to fill up a pug group for it, despite having done many successfull pug groups and clearing it, it toke double the time it should have taken.
i dont see a future for a 12 man dungeon wich will require 12 players to clear.
it will simply be deserted unless its overly easy like onyx or dumb content like that.
and no way in hell will a 12 man raid be formed in guild for it, would actualy help split guilds apart if content was too hard you would prioritize best players leaving the underperformers behind, while right now pretty much is half the raid performs accordingly there is a lot of room for underperformers to tag along wich is totaly acceptable even in t4/erlic and makes up for good guild content.
