Match History
Just as with Ashe support, your ADC will probably rage at you when you're not premade.
It's understandable, but just do as you always do: hands off the minions (unless pushing), peel off the enemy team so your team can last hit, or you can take them when they don't finish. On laning phase, make sure you ward river and ARE the ward in the bottom bushes. Peel off the enemy (preferred) ADC with auto attack + Q. Keep doing this and they will get scared of the bushes. Because you have river warded you shouldn't be too scared of enemy ganks, W (and if you have to, Flash) to get out when they come at you. Turn with Q on the enemy ADC/jungler (depending on who is closer) if your ADC decides to fight, or do it while fleeing to your turret.
When lv6, bomb the river (including the bush + tribush) with shrooms. If all goes well, enemy jungler won't even bother coming because of that xD
And if he does, you or your ADC might just get a triple kill out of that
or you can let your own jungler clean up afterwards. Doesn't really matter either way.Depending on how your game goes, and what the enemy builds, you might need a Zhonya's Hourglass or Abyssal Scepter. Maybe even both.
Is your team fully retarded and not focused? Consider a ZZ-rot portal to push lanes to get objectives (turrets ofc).
