I've seen this aversion and honestly I think everyone is entitled to play however they want. Adding on requirements to have outside resources to play is not conducive to increase a game whose population is mostly returning players that more than likely relied entirely on in game chat and emails to communicate. For new players, this game probably seems a little archaic on that regard, but communicating over headset can really improve coordination during play. Just look at PvP, where spiking damage on a target (i.e. everyone activates their attack at the same time on a target to maximize damage output and defeat the target). Or 'Master of' badge runs, where defeating an enemy or staying outside of a killer beam is paramount.
