Increase monster spawns in guild dungeon
Guild dungeons spawn amounts are really low, they are supposed to be high risk, high rewards kind of places, in their current state, the mob amount is too little. Monster spawn numbers could receive an increase of 25~50% depending on the dungeon, this is something that can be finely tuned by trial and error.
In the current state, Guild Dungeons are worthless to even visit, just to kill the 8 hours respawn MVP and maybe attempt to hunt a card (which all of them a PVM cards), they are supposed to be relatively hard places to survive but with a high payoff if players are successful. Plus the PVP should make it a little bit more interesting.
Some monster drops should need to get revisited because they might cause some imbalance, but I don't think it is really needed.
