It's sad to read posts like that in a team oriented game tbh. I understand, that certain people want to finish stuff as quickly as possible. On the other hand, I have experienced, that people learn stuff differently. Some get it first try, others need several attemps first in order to get the full picture. I personally belong to the second category. When in a new raid encounter for example, I first need to see stuff like overall encounter flow, enemy density and enemy spawnpoints for a few times to get some orientation before feeling comfortable. As you can imagine, this doesn't go too well most of the time. I had my fair share of toxic raid groups back in D1 so I didn't bother with them in D2 anymore. So far one (!) RoN clear, one Vow final boss encounter and one GoS run until the final boss, when some people had to leave, that's all. The same goes for dungeons, one complete run through the Caitl one (just can't remember the name) and one final encounter on the Seraph one. So practically no endgame for me. I don't care, though, because I value my sanity and a good time while gaming more than certain loot and I'm not willing to cope with unmannered toxic individuals anymore. Solo forever and by the way, I'm 50 years old and see my reflexes dwindling as well already. I sincerely hope, that you can draw fun from the game nevertheless, because that's all that matters for your time spent in the end.
