No reason it should lose to batman's double jump. No I'm not gonna let it go when my move fundamentally does not work properly lol. It's been relegated to a combo extension only and that just feels uninspired.
Take your negativity elsewhere, this is a discussion, not whining.
No, the negativity belongs because, like most threads concerning what a character "needs," it's a non starter that ignores a character's strengths and overall addition to the economy of the game in favor of fitting the character to a player's personal grievances that should have no bearing on balance in the game.
Like this Lantern's Might thing: we have hyperbole to the level of "my move fundamentally does not work properly." What in God's holy name does this even mean? Does the move cause GL to t-pose and crash the game? Do interactibles stop working if Lantern's Might is used? These would be "fundamental" issues.
What I think is happening is that every time the move does not connect, which is almost always an error in the player's assumption of where the move hits, then that for some reason is shuffled into the category of "lol stupid move isn't even working." And that's fine for the recesses of your mind at 2 AM during a 1 and done ranked match, but it doesn't hold up when under serious consideration as a "problem" for GL.
Go to training mode, and test out a bunch of scenarios of where it hits, and where it doesn't. Old school, I know, but we don't have a hitbox viewer so them's the bricks. It's pretty clear after doing that that the move hits in a sort of rectangular region starting from the middle of Lantern's head/face to probably somewhere close to the bottom of the screen. The max extension is just a little beyond his arm, and nothing more. The move also has 4 active frames, so clearly if it's going to be used beyond combos, there's a precision in the use. Unfair? Maybe, compared to top tier derp, but in no way does this move strike me as "broken" or having "hitbox issues." It's just maybe...not as good as IGAU? And maybe they kept the longer range to his trait to make it stand out? Fuudo for thought.
We all know the Fred Marvel schtick by now: for some inane reason, he has decided that he is this great, top level player held down only by his character choice, and that the character should justify the way he plays in the way that he wants. Again, this is all well and good in your head, removed far away from scrutiny, but he has decided not to do that.
As such, threads like this pop up, and it simply exists as a hole where good discussion goes to die because hardly anyone is looking at balance from the perspective of what could actually be beneficial for the game. I'll quote Keits on this subject:
"If winning with your character is fun, then the best 'balance' for you is your hard matchups to get nerfed, & you get buffs. This is, as i said, a selfish view of the product. A game designer cannot think this way."
The discussion will only get better once people get off the train of "this is WHAT'S WRONG WITH GL" and start thinking about where he plays in the overall economy of the game. I very much doubt that time will come to pass.
