EdyLKincheloeHmm... Maybe a nice sponsor to put a little incentive into winning Platinum..?
Considering you need to be really good friends with the IM/Main/Invite players that make up high platinum and are the teams that win plat or you need to have experience saying to these high tier plat teams that you can play in this level isn't easy at all to really get coming out of gold. You can't just move up from high gold and consider yourself already a good enough player to win platinum, just doesn't work like that.
While what you're saying is true to a point, as a team leader on BPM I make a point to try and pick up backups with potential. For example, blam and Feint are 2 players I recruited onto our roster with little to no comp experience, and both do great in Plat scrims and matches. Feint is playing in Gold now apparently (that kid's gonna wreck) but the point still stands.
And, Edy -- you were one of the engis I would have considered asking to backup engi for us, but sodapopinskii is literally the most reliable team player I've ever seen, I think he's missed one scrim in 5 seasons.
