hooliunless CEVO makes their service significantly better than ESEA's; that's how things are going to be.
That's the thing.
ESEA is scattered with problems even for the most general things. Laggy servers, horrible connection leading to bad ping, no exceptions rules, lack of updating stats, no team move up rules (except for invite) which causes sandbagging, taking advantage of monthly premium costs.
If CEVO manages to have none/few of the problems that ESEA has then I think CEVO's service will be significantly better than ESEA's.
