for quest.

[Boubble]

you cant know if its the clan wars that new people would like (i doubt it for the high skillcap) or the quests. either way, you cant force players to play clan wars. period. if you remove quest, many people will leave.
quest is actually a good solution for new players who want to get ot know the game, because PVE monsters are easy and predictable.

The amount of people joining GunZ at this stage is very limited. It's not a matter of what new people like, it's a matter of what attracts GunZ fans hence old players who knows the game. New people don't know shit about the game. If quest mode wasn't a thing, they would probably just adapt and play deathmatches, duel, clan wars and so on.
