Exhaust Vs Ignite

Invalidating an assasins burst for a few seconds is pretty good to me.

But sometimes i like to use it as a bit of extra CC to secure a kill.

I always run exhaust unless against some shit like sorakacare, but i mostly play mage supports that dont need/cant get close enough to use ignite..

I imagine the meta shifting towards longer games (seems like a goal) would make exhaust more favored.
