I did sunken temple today as a summoner, I can't imagine a dungeon much less favorable to a pet class than sunken temple starting with the very first boss... Then you have a pet chasing down a mob that runs at low life... then you have mobs that have to die in exact positioning or they respawn.... First boss is death to pets, maybe they need to turn up pet's resitances even further to include something like doom... But even then we still beat it and I didn't feel like a hindrance to the group. Every other fight since hitting 30 I had been playing as a Scholar. I do think the lack of burst is a little bit of a problem, on the last boss, the verge's need to die preferably within 5-6 seconds, but more realistically within 10, either way, WAY too short a time for dots to be useful, I basically just sicced my pet then started trying to ruin, energy drain, then ruin again. If I had ruin 2 I'd have been spamming that, which actually would have been fine I think. I do think sustained against multiple mobs is pretty high, as well as on movement fights. On a longer "burst" phase, such as the rock golem boss with the soulstone, I have no doubt that a BLM would run out of mana prior to reaching the end of the "burst" unless they get lucky with firestarter/thunder procs. Especially since it allows a summoner to preload 3 dots via the bane mechanic at the start of each burst.
