Most melee ad champs that would need it would be broken by it. An ad champion that needs untargetability is likely an assassin who just deleted his victim. The drawback of assassins is a lot are deadly going in to the point where it's almost unfair, but struggle to get out (Excluding
....). Take
for example. His ult can either be used to get that jump on someone with invis + some extra damage, or he can save it and try to kill a carry then ult out of harm's way until he can do it again. If
could ult in and pop you, go untargetable, then slip out, there is no longer a decision to be made and some balance is lost in the fact he gets the best of both worlds. Imagine
with a second untargetability O.o or what about
O.o
can already dodge his weakness (cc) with a q and if he can dodge all cc with an item that lets him go untargetable for a bit, he would literally be unstoppable in most scenarios.
has a shit ton of dashes and damage and essentially always has some dash off cd, but in the scenario
doesn't have her dashes or is low and needs to buy a quick second for her short cooldowns, she would be able to just go untargetable and never lose because she has an item that lets her blow her stupid strong load on you, wait for it a bit completely safe, then blow it on you again. You are seeing the issue yes? lol And you might be thinking "Well what about ad melee champs that aren't assassins or caster-like? Why can't they have it?" Well put simply it's an illogical buy. An ad champion that isn't an assassin is gonna be front line with some damage but tankiness to peel and engage and such (
). The item would in no way help them fulfill this role because if your tanks/fighters are in stasis guess what they aren't doing? Tanking or fighting for you! XD A frozen person who can't even be targeted is not providing meatshield, damage, cc, peel, disruption, etc. It would be smarter to get tank items for defence so that they can keep fighting while being protected instead of buying a quick second for no reason and leaving their back line open to attack. So tl;dr, Any melee ad champ that it would make sense for them to buy it would break the game and the rest just wouldn't buy it.
Edit: Idk y but i feel like this reply might come off a bit hostile? If so know that's unintentional, don't mind my wordings lol
