The Fallen Avatar fight is by far my favourite boss encounter in ToS. Once Phase 2 begins, there is a sense of anxiety that's almost exhilerating as the floor beneath our feet begins to break - it's a good ol' DPS race.
Kil'jaden, because it's about time we get to finally face him and beat him up.
Desolate Host. The coordination you need from the two groups is rough but satisfying, and then the 2 groups fighting the same boss mechanic was something fresh and exciting.
Maiden, the pit with the holy/fel charge aspect is fun.
Desolate host put the two groups in friendly competition mode, that was awesome.
Maiden, since as a tank it's really easy, and I can relax for a while.
Desolate host by far has been the most fun (next to Kil'jaden). The two realms and the mechanics for each realm is quite fun as a healer.
Goroth is the best boss because he is a piñata full of loot.
I love the KJ fight. The mechanics make it far from a boring tank and spank and the lore that has led up to this point is so great!
KJ is my favorite boss, because he drops lock soul shard gylphs
We're only 4/9N right now, but I'm a fan of the Sisters of the Moon, the moon phase floor mechanic is really neat, and I can usually cheese through that nasty shield/heal ability as a warlock, between self-heals and absorbs, as long as I'm not near anyone else exploding.
Id have to say the Desolate host. Its a great throwback to the original encounter in black temple to where one side is dealing with the living while the other side is dealing with the dead. From a healer stand point its frustratingly fun because this is more so a Trust" mechanic with your other guild healers. It was so fun we made it a partial game of war betweeen the healers and made tomb more enjoyable.. Until we wiped LOL!
Harjatan and Maiden for me. They both let you know who in your raid is actually paying attention really quickly.
Maiden of Vigilance for me! I wasn't expecting it, but that fight is just plain fun to play.
Nobody expects the DEMONIC INQUISITION! Very fun fight.Second would be Maiden, because who doesn't like simple mechanics that will instantly wipe your raid.
Kil'jadenIt's great to finally be able to kill him "for good"! Plus the cinematic after the fight.
Maiden is my favourite, because of the orb dodging and bomb jumping :) oh and she also drops her hammer as a transmog
I love Maiden, because I think the mechanics are fun, innovative and challenging for the entire raid!
Fallen Avatar is the best by far. Solid fight with easy to understand mechanics, yet difficult to execute correctly.
Favorite boss so far? Goroth, because that's all I've tried, lol.
