I played a couple of rounds of Solo Breakthrough after the connection issues started yesterday as it was the only thing that seemed to work. Imo they should have just let people who want to play Solo/Coop have acccess to all guns and attachments from the start in solo and then completely remove the ability to earn exp from bot servers.
I can't see how any Exp/bot exploit you could make in Portal could be worse than Solo Breakthrough. You can go on 100+ killstreaks relatively easy on those servers. But to be fair there's too many actual problems at the moment for me to REALLY care what they do about bot exp.
