I'm so sick of this blue>red>gank bullshit. I've used to stand on bottom line with Karma (i'm twitch) against pantheon+rengar, the pushed line to lvl2 and instant gibbed karma who thought it was fun to stand in range of pantheons' leap. I've retreated to my tower and tried to lasthit in safety. There is where our Shaco came up. He've got red buff crossed middle lane (creeps have seen him) and walked through the river pinging me to fight. Two bruisers of course knew about Shaco since their map awareness was on higher level than usual silver player and as soon as Shaco jumped in and lost his stealth, i opened up on rengar but Shaco died instantly and gave away 2 buffs to panth.
TL
R DON'T gank 2v1 lines when you are lvl2 assassin it doesn't work like this, you need to be at least level above than 2 enemy who share exp
