erm snipe does arround 330 at close range like that and if ur out of her sight range then shes out of urs and plus on most maps u can get a double team situation like that
is she going to just sit there not doing anything then start running she'll proberly have a army of creeps and munch a shambler and then she will tank till shield is ready shield her self then hol back to full and kickone of ur asses then retreat back into the safety of towers re shield munchs a shamble and charges into the other dude
see u can't say this is how it is going to happen because that would be highly unlikely 2v1 in a what 3v3 on cata and prison is highly unlikely and the way u said it the other dude is going to appear out of no were
that would mean a ere which would get owned by the creeps and which this is all happenigng ur 3rd will have died and your towers would be under attack
