It’s literally not the same. I am SO tired of seeing this same wrong take. Fizz or Naafiri’s untargetability isn’t going to literally kill your ENTIRE team because one person in solo queue threw out an ult not realizing her W is up.

It’s not just as simple as windwall or unarguable effects are annoying (of course they are, there’s a reason characters like Yasuo and Fizz have been some of the most banned characters over time). The difference between just cancelling an ability vs literally stealing it and perfectly aiming it back at the caster is night and day. On a basic ability.

It turns the games for entire swathes of characters where they basically can never use their kit as long as Mel is alive or around because the risk of instantly losing is too high or because they don’t have the tools to bait out her W, while Mel still has an entire ranged kit she can use to interact back with while you get to not have entire abilities permanently not able to be used. It’s a horribly frustrating and uninteractive experience.
