I've been considering OP's words for a few days now. I can only speak from my personal experiences. I'm having "fun" as it stands right now, but I'm not facing any kind of challenging content that requires razor-sharp precision. I raided at a very high level in WoW for a number of years, so I can understand what he means though.

I suppose I wouldn't care about server upgrades, if the content is aware of it. I really don't care for obscenely difficult content. If the boss mobs and NMs are "easy" enough to be defeated without janky cheating or exploits, I'm fine with that I think.

Though on the other hand, it appears that is not the direction Square is going, considering that random crashes happen and completely throw the player from the instance, making the boss fight nearly impossible.

tl;dr, crappy mobs on crappy servers need to be forgiving of players trying to work within the system and die quickly.
