HellbentI notice that a lot of times what separates an IM team from an invite team is simply just having more solo players that play for stats, dont comm, and/or dont listen to comms. There are a lot of those players out there unfortunately.
I think a perfect example of this (at least in terms of solo play) was the old goldfish vs. Slamberg battles in IM. Both of them used to just try to do all the work, they'd always be the one making plays, or in behind distracting.. and honestly, it worked a lot in IM (and was awesome to watch). But moving to Invite, you find that teams learn, adapt and adjust so quickly, that you can't get away with just big dicking every life - you'll just end up salty with like 60 deaths. It's been cool to see them, as well as some other players, grow and evolve from a solo/hero type player, to more of a team player after making Invite.
