DFG - an item of value?

I think I´ll start of with a comment from Pwyff on 3.13 and DFG:

I'm not saying that DFG pidgeonholes champions into building the item but a lot of the time if assassins are strong then the competitive meta can get focused on who manipulates DFG the best. Syndra does build DFG more often than the others on your situational picks, and Annie / Veigar are unpicked for other reasons. LeBlanc / Ahri / Syndra (sometimes TF and lategame Fizz) do build it and those are the AP assassins we'd probably see come up if they do get strong. Even Lissandra there's a very real danger when she gets played that she instead goes for a DFG and blows fools up (as someone put it).

I'm not saying it's as black and white as pidgeonholing but I am saying that the danger of burst mages rushing DFG is a pretty unhealthy world. We'd instead prefer to have that power on the mage themselves."

I think that pretty much sums up my problems with the item...it only seems to create cases of abuse, but doesn´t add anything to the gameplay.

• It makes killing things quicker ->less reaction time ->less counterplay
• It allows for more sloppy plays ->still seeing many deathlogs when Ahri missed q and e and killed someone only with the non-skillshot dmg from r+w+dfg, same for other DFG-(ab)users ->in a way rewards overly for making misstakes ->amplifies snowballing
• It´s not at all hard to use, it´s just one more button ontop the usual combo

So for me personally I came to the conclusion it would most likely better to just delete the item and think of a new 120ap-tier item that really brings value to the game. Or is there sth. about DFG I don´t see that makes it worth having it in the game?
