having a fourth race would be a very good addition 2 this game. their is so much u could do. if its a mix of zerg and protoss(which it would b, dats wat happened at the end of sc1) it would have 2 b stronger than both the protoss and zerg so they wouldnt have 2 balanace it out. makin it realistic would mean that the three races would b even but this fourth race is sumthing new, sumthing powerful. they should cause fear and panic among the other three races, particularly zerg and prototss. but at the same time they should also have a weakness 2 sum particular units of the zerg and protoss(like maybe reaper bullets do a little bit extra damage to just this new race...but the reapers die just as quickly), like the newer ones, being that when they first merged wit the races those units werent their. that way they would b all powerful but still have weakpoints.
