I do not think the team fire meta will leave. Does anyone, really? Wether D1 or D2, more people firing equals enemies dying quicker. Now that the habit has caught on I would believe it's gonna stick around for a long time. What's the downside to sticking together? Getting Breaker'd by a rocket? Hardly happens, is easily neutralized by racking up kilsl as a team. Getting team wiped by a super? Yeah no in D2 energy weapons shred anyone out of their super before they know it. I'm more than OK with being proven wrong, since I'm really sick of how D2 PvP plays out. Not even at its worst was D1 this monotonous and unfun.
