Sorry for explaining myself poorly, my bad! What I tried to say is if he for example pushes to heaven as a T on Nuke and dies there, he still made sure there's no one in garage or in any place close to that, which makes it easier for everyone else to move around the map. I would say gaining that much map control is a lot more beneficial for the team than him dying there without a trade.
And no, I never had any problems with ISSAA - I actually really liked everyone on the team. :) ISSAA had his problems for sure, but no point blaming all the team issues on him. Playing with bad ping from Jordan and constantly getting shit on will make anyone play bad.
