Right now not really, as the VOIP options turned off also turn off the chat, you will probably find that 99% of people can't see chat. I have it off because it's crap quality and listeneing to the infinite number of numpties who have no idea they have their mic on in co-ops or pvp is insane, the quality is bad and I use TS with friends.
It has the worst social system in any online game I have ever played in my entire life, it doesn't even try to promote this. I honestly give this game a few months/until after the first season airs.
I'll have to compile a huge list of issues with it, some personal opinions of course.
I disagree, the time vs reward on arkfalls are bad, it can take up to 20minutes getting a 6k(?) xp rewards + mobs, a lot of which are high HP elites with very little reward.
You'd be better farming that hotshot minigun repeatable quest for 2k xp every 2minutes, you don't have to travel, you don't have to wait for spawn. But it's boring, but so are arks falls after they all seem to take 15-20 minutes.
Doing side missions shouldn't help for main quests necessarily; I've still yet to replace my starter LMG (except I need to use a different one to level LMG skill) as the best weapon because even epics/legendaries have that rare chance to have really bad stats or fire modes. Weapons don't really get that much better from 0 - 500 rating so far, it's tiny stuff like nano chance (fire/electric etc), maybe .1% more crit or 20 more ammo in the mag or less bloom/recoil. Not sure what'll be like at rating 1000-2000 :X
