My first thought is, 'why in the hell would extremely powerful monsters just magically appear in the overworld?' One or two random 'i appear in overworld and i'm gonna kill everything mwahahahahaha' might work, but this isn't your typical MMO.

My second thought is, 'either we'll have to see a balance for a fight that can host more than four players, or try to make the game able to handle numerous fights at once.' In fact, I don't think we should even touch 'raid bosses' when SL2's endgame offers little to begin with. (especially where challenges towards a party is concerned)

My third thought is, 'there's still going to be a lot of work making something that acts something like a raid boss, unless people just want a huge damage sponge that dishes out stupid amounts of damage with the occasional jacked-up rampage.'

TL;DRA raid boss isn't a bad idea, but it's going to take a lot of work to do, and I think we have much, MUCH bigger fish to fry before we start trying to make official raid bosses.
