The lack of working reserve power totally changes the game. Normal pen and paper tactics for hydrans is to keep the fusions unarmed until in a position to use them, and then instantly charge them from the batteries and totally ruin some fool's day. Romulans also get hit hard as their ships have a large reserve power bank in relation to other races. Also, races that get more than one point of power for each battery, such as the andys, won't even work.
