Have no idea what you are trying to say after reading
Loved the game back then, still loving it now, nothing changed in game, everyone started from fresh so everyone is same
As for the bosses, most of those you can either kill them and ignore the adds, or just hit and run around LOS heal yourself, I never do them as waste of time
"Bosses (or even mobs) that can barely be completed alone. Yet beating these NPCs are required to complete quests, gain XP and progress."
You are just ranting now are you?
There are probably less than 0.1% of the quests in the game that requires you to kill a boss, if you can't do it solo or find a group, just ignore it. I am 1000% sure this game DOES NOT REQUIRE you to kill these few bosses to gain xp and progress
