Each character must have 3 styles, right? If Rain is in, 1 style will be based on his water powers, 2nd can be his classic moves, but 3rd must be based on electricity, right? Then you have Raiden, who also need 3 fighting styles, all of them must be based on electricity, Raiden will likely use all electric attacks NRS is capable of imagine, which leaves nothing to Rain...it's like Sub-Zero/Frost thing - if more popular character of the same powers is in MKX, less popular is doomed. This is a 1 single reason why i'am not so crazy about 3 fighting styles per guy, leave enough of characters without a chance of appearing.
