unfortunately i don't have any endgame toons yet (rolled my fixer in 06 and she's still only lvl 100... i predict i'll finally get my doc to tl6 by the time 2012 rolls around) so i can't comment on the difficulty of the raids, but i'll take your word for it. if it's too easy it definately needs to be harder. however coding AI in this 9 yearold game might be a bit of a stretch especially with the upcoming engine changes... maybe with the new engine we'll also get smarter AI and that'll solve that problem. only time will tell, i guess...
speaking of changes, seems like with the Great Rebalancing most professions are getting a nerfbat to the face so raids might get harder because of that (healing nanos cost increasing, enfos HP decreasing, duration reduction on roots/snares, etc)
