"Exauhst is useless late game." exhaust offers 50% damage reduction from whoever it is used on. how is that useless late game? if someone gets hyper fed on the other team, one of the few ways to deal with them is to use exhaust to drop their dps to a level you can deal with. supports arent meant to be split pushers. their main job is to peel for the carries or to help engage/disengage a teamfight. during laning phase you need to help zone the other team to let your adc farm, and to try and setup kills for adc so he/she gets fed. thus a support should run heal/exhaust/ignite and adc should generally run barrier/heal/cleanse. if the adc is running heal the support should not as a general code, because double heal isnt that effective. exhaust is very good for early game fights as well, and early game kills can help late game scaling adcs jump over their slower start and be able to deal with lane bullies, or get to their power curve early and carry the game. generally the split pushing role is left to the adc/top/mid as a split pusher needs to be a powerful duelist to really be able to put pressure on the map.

Gr8 m8, I r8 8/8.
I may have missed some of those points. :P
Double heal USED to work before it was nerfed.
