Disclaimer 1: I don’t say “It’s too difficult”/“Nerf it”/“I can’t do that”. I can and I do that successfully with all the different characters.
Disclaimer 2: This is my personal impression, I’m not implying you should think or feel the same.
Among different roles in this game and many others I definitely prefer attacker’s role. I like to kill enemies and I like to do it fast; however, I’m not a risky man, if being a good attacker requires me to be glass cannon I rely on my knowledge of game mechanics, enemies behaviour and environment to compensate that “glassiness” (I also love life leach attribute). But I’m not a fan of surviving at all costs, kiting and so on - shooting and punching is what I play this game for. I’m also a kind of perfectionist/control freak and I don’t like chaotic fights, unpleasant surprises and one-shot deaths; all those luck-based events in general.
As you might understand, Aria’s fight doesn’t quite favour my preferences. Almost all the time you have to do many things at once: kill adds, kill anchors, watch boss for her powerful strikes and dodge them, watch the ground to avoid being hit by arriving anchor and even watch two bosses at once in the end. Oh, I forgot one little thing - you also have to keep hitting boss, because it’s your main objective - to kill her. And my mistakes are likely to be punished with a hit of more than half of my health or even instant death.
With all those things happening at once I have little time to learn boss patterns, adds spawns, anchors spawns, timings, etc. In order to learn how to perform a “clean” fight, a fight that was intended by devs (if it was at all…), I actually have to stop fighting, but it’s not quite what I play this game for.
And with a team everything becomes even more chaotic and each mistake results in an even greater punishment. Like it wasn’t enough already.
It’s not like I’m constantly dying, not at all. 2 deaths is my max so far, average death count is 1. But, because of its very nature, the whole battle going feels dissatisfying to me. And even if I managed to do a deathless run, it feels a bit like it wasn’t result of my efforts but just the luck.
I just beat Aria with Caldarius at 100 OP and died only once, and you know what? I say - skrew that. I’m not going to do that anymore. Until I have like 2 lives left by the middle of the fight (that, you guess, is impossible at current difficulty), I’m not going to spend my nerves trying to suppress the pure chaotic nature of that fight, to avoid insta- and nearly-insta-deaths and stuff. My skill is enough to beat the boss just by unleashing all the damage I have with my character - without taking care of surviving. Since it doesn’t help much anyway and a few deaths won’t fail the mission.
This boss discourages me from “clean” fighting. Why make an effort to fight properly when it gives so little result? I don’t like that too, but between these I choose the easier way.
P.S. If you want to ask me what I suggest to improve, at first I’d prefer to see a video how the designer of that boss does the fight. With a ranged and with a melee hero. Probably with a team of 3. Maybe it would be enough for me to see what I’m doing wrong or to make sure that this fight was initially intended to be exactly like that, and thus, doesn’t require improvements.
