A great trick for bot lane if you are support is to act like you need to ward again. Bot lane combos (especially balls deep engage comps) will go on your ADC like 90% of the time in baddy mcbad Elo land (aka my place of residence).
Yeah that's cool too though some players won't draw the conclusion that you're warding and it's time to harass you.
Pretending to be a bad player and standing in line for skillshots and taking actual damage is the best bait. Bit of an investment to get Rocket Grab'd but still.
