1.I for one respect 1v1s for the most part unless im ganked at them and then i see that creep or freep 1v1ing then hes open game.
2. Well in all fairness some people they dont believe in 1v1s so people cant honestly get mad at them about it, its just not their playstyle.
3. Now however from time to time you see some who are into it then feel the need to gank when they feel like it, well ive got a policy for that for the most part i just kill them.
Lastly your best bet is always have people around you and if its scoobie or another who does it well just remember in turn when they decide to have a 1v1 and give them a taste of their own meds.
