I think that mouse need a experienced player.
Acor, RopZ and Frozen are enough fragpower, but the only one that IS experienced enough is ropz, but he IS Young.
Dexter hás no experienced in tier 1.
I would put bymas 6th player só he can develop more. Só I would put a Very experienced player like nbk, Sunny, flusha, Fer, olofmeister.
The experienced player would Help the team If something os wrong thing Also Help dexter tô IGL.
