I just tried to complete the Twilight Oasis on Tier 3 with a full group of extremely well-geared and experienced players, and it was the most unfair and boring experience I have had so far. The final boss "Amala" has WAY too much AoE or too short cooldowns on her attacks. For me as a druid healer it is literally impossible to utilize my class in any way because all I can do is run around to avoid AoE's and try to revive people, but even that is impossible because Amala keeps throwing so many AoE's literally EVERY second. This fractal needs to be more friendly to all the classes and that boss needs a serious revamp. The AoE attacks are fine as long as we can breathe for at least a few seconds in between to actually be able to use some skills, ESPECIALLY for me as a druid. I was completely useless. I also began to explore other flaws during the fight and whaddya know? The AoE's hit you even when you're NOT within the enemy AoE fields. This happened so many times I can't even count it, so not only are the AoE's eating away about 70% of your health in one swoop, they happen EVERY second without any form of cooldown or short pause, they also cover the entire room except for a few holes in the AoE fields on the ground where you can stand to avoid it, but that is also useless, because like I mentioned, they hit you even when you're outside them. There are many elements and factors to this boss fight, but the AoE's do not need to be like they are to make it more difficult. And if we bring in some mistlock instabilities as well you can be certain that it is literally impossible unless you're either lucky or spend 3-4 hours on that same fractals trying to complete it. Nobody wants that, and while a challenging game instance is nice and fun, this is not challenging, it's just unfair and infuriating. I am mostly saying this as a druid healer mind you, because I want my class to have something to bring to this fight. My healing didn't even do anything because of the relentless attack cycles so there NEEDS to be a pause between some of her attacks.
I may get some criticism for this post, but I don't care. This is the experience I had, it is my opinion and I stand by it. Twilight Oasis needs a nerf.
