My biggest issue with GA is how
can place a trap under you. You are revived, trapped, and then killed. I think a split second of CC immunity would be welcome for the item even if the cost was raised. It can be really short but something would great.
The biggest problem with the item in the past was that is was terribly costly and the passive had a pretty long cooldown. No one really bought it. Now it is a reasonable item too buy with the cost being lowered and the passive is at a reasonable time.
It definitely is a situational item, which is what it should be. But if you are not a tank your survival post GA is pretty low.
Sometimes when I play with friends they ask me "when should I get a GA?" or "Should I get a GA?"
I think a good rule of them for when a player should get a
is "If you cannot afford to die." Basically if you die the team will lose because the game has gone on that long. ADCs often have to decide whether to build damage or a GA. Typically if the ADC is facing assassins and a team is not peeling very well you buy GA, have it proc, and then sell it and buy damage.
I also think it is a good item for an ADC that is really ahead because then killing you becomes even harder.
