It is too easy, even the bosses in EV hardmode is way to easy imo.
Its all about making the enrage, no really hard mechanics to get past. Which is really really sad, if the next set of bosses arent more interesting this game will die out when it comes to progression raids for sure.
Nightmare Soa Kill kthnxbai?
Anyways, being 4/5 Nightmare mode myself in one night I will agree with you the HM's/NM modes are too easy, but we do need to remember this is the first tier of raiding and we can't expect the difficulty of a boss like Heroic 25 man LK in WoW or Heroic Ragnaros if you still keep up with the game. Yes, I got 3 Rakata tokens in one night as well.
Lets wait and see how the extended Karraga's Palace is on Nightmare before we continue to judge the first raid of a two week old game.
