3 dps, 2 heals or 4 dps and 1 heal, should not be able to steamroll endgame content..
I know we have only 1 dungeon but the trinity is not even needed in the only one we got! There are no aggro checking mechanisms in the dungeon although there are some Heal and Dps checks!(this is great! good healers are needed).
1.Add some Powerfull attacks on elite mobs and bosses through the dungeon with fixed 400k or 450k true damage(you can fix that number) that cannot be dodged or Scrolled after dying(like coocoon)
2.Remove the ability to swap roles in private Q.
I know there must be better suggestions and solutions so let's work this out !
Sorry for my bad English
