3v3.. shud b 3 lane? if om @_@

generally,
gb not so easy die.
rax not so easy break.
tower easy break.
but when any rax break = GG.

some silly example:
a healing-p combo? omni,necro,priest?
an aoe-p combo? treant,tide,dp? kill 1 by 1 (but consume ulti)

but my opinion, kill 1 by 1 is the best... 3-1=2, then 2-1=1...
when 3 v 2, big big diff... tactic very important.
