How is this a team game?

[Necrontyr]

sadly there are kill hogs in this (ive been one from time to time) but usually to rank up just standing near a player get a kill earns you assist xp i do believe, ive only just gotten back into this from a year ago so not sure about that.
and yes teaming is bloody hard to organize since games usually result in the higher lvls running into swarms and cleaving all the easy guys only to die on high lvl enemies which murder the low rankers.
