Did AoI used to have sentry? I don't really understand the point of this champ anymore, but I know it used to be in a lot of my BGs. Does anyone still use it for anything? What champs do you sacrifice to the flag? And is it worth it? I thought it used to allow supportive abilities before, but I could be daydreaming. Seems really expensive to make a champ able to do nothing but move.
I've never used Flag because of it's cost, nor used Aspect of Infinity after it being mutilated to it's current usability.
