A while ago, 2 of my friends got into destiny and we've been playing together and messing around as a fire team. Recently another friend was interested in the game and got a copy. However we came across an issue. We cant really do anything as 4 people besides comp,gambit and the occasional raid. I think it would be great if bungie could implement more than just 3 members in strike, quests, missions and other pve activities. A cool idea might be to proportionally increase the difficulty of a certain activity against the amount of players playing which would then grant us a better multiplayer experience.
Don't you worry. I'm sure BUNGIE will grant your request. BUNGIE cares more about groups of gamers than it does solo gamers.
