I could be wrong, but isn't this strat about as old as stone, or am I the only one thats countered this strats half a dozen or so times...
One nice thing about a (non-fighter) rush though, is all i have to do is beat you to the punch by 1 minute. So if enemy team see's what were doing 1 minute into the game via a scout - and tries to counter w/ the same exact strat, we'll have dd's/ions 1 minute before them and be able to pfft their colls and cc's before they can defend. Hyperspace costs and mob costs, don't slow down the time it takes to get an adv or dd research for the team. Only real slowdown is the time it takes to jump, but on smaller maps this isn't even an issue, and on bigger maps that extra jump time more or less equals the time it takes a scout to cross the map. Bottom line is you gotta react fast and rally your team to counter, and just because i don't have that silly Big Add Possie tag nxt to my name doesn't mean i'm not pro at doing that.
