Bring back Deathfire Grasp (DFG) for testing?
Honestly, while I do understand its removal way back when, I think it could have a healthy spot in the meta with some tweaks. The removal of DFG wasn't because the item was "too powerful", rather "powerful enough to enforce a meta". Such a thing, with Stormrazor and Duskblade already out, would hardly become consequential in a meta sense.
However, the specific reason for its removal was because DFG standardized the meta, it "removed diversity". I would argue the exact opposite. DFG allowed for so many things to be playable, from AP Rengar to AP Shaco, anything really worked. It allowed for a fun environment where you could basically run AP regardless. And, given that mages can build AD and get away with it (ADC Ahri really shouldn't work, but it does), I don't see a reason why vice versa wouldn't be true.
If the item ends up being too borked still, of course, remove it. However, I think it could find a healthy place after hundreds upon hundreds of changes and mini evolutions have happened to this game. Why not give good ol' DFG another test run? I'm sure it'd make a lot of players really happy.
which has been an issue since its release whatever is its effect
while
became pure shit
