The devs fix stuff constantly. Almost every update for ages has had at least one bug I've personally reported fixed (if not multiple). Depending on the nature of the bug and the quality of the bug report information, things tend to get fixed. Sometimes not at the rate I'd prefer and sometimes there's bugs I'd would rather have a priority over the fixes that happen; but that's just where I rate importance of things, not an absence of fixes.
Then why the game still freeze from time to time while I'm playing during hardcore season? And I do have to restart the game client (while the mobs on hardcore are still beating me while I relog the game).
Why when I restart the cliente from time to time the chat is not available for many minutes? They said they fixed it but the issue is still there?
Why they didn't fix energy vortex issue mentioned by me above? It has been released years ago.
Why they didn't fix Primal Avatar Thunder Snow sla? I mean, have they ever tested it before releasing it years ago? It should "Send forth a wide wave of freezing hail", let me see the ******* wide wave of freezing hail ahahahahahah
At R10 difficulty the only reliable thing in this epic destiny system is Dragon Breath because the things mentioned above (and many other things) are bugged and the developers do not fix them.
I was recently considering to give a shot at "Holy Fireball: SLA" in Exalted Angel destiny tree but I just read that they will nerf it too: I mean, what the hell, it's a tier 5 epic destiny sla, what's the need of nerfing it? I never heard people telling that it's overpowered (fire element is also resisted a lot).
The truth is that the developers MAYBE fix something that has been released from a few days, otherwise they care only about the next update development (new packs, new expansions etcetera) and they forget about older stuff: this is not the way to maintain a game.
Also the only thing that the developers fix is the ones like "now you can buy stuff from the hardcore vendor": I mean they have to fix stuff like that, otherwise what's the point of an hardcore season if you can't claim stuff when reaching the reward point?!?
