I guess lighting needs it to lower it's recoil, given it's much lighter weight compared to wheels like vulcan and gravity, and current defense combos. I'm not great with physics, but I guess tge right balance between speed and suferring less recoil (as to direct it towards your opponent instead) has shifted.
Wonder about Beat Lynx's track, though, if it weren't attack, I'd guess ch145>230, and seeing as ch90 is probably a technical impossibility... Maybe it's a different type of height change, like a mid battle thing like f:d. That'd be horrid, and I'm kinda expecting it. Or a fused height change, might mak ch90 possible, but still, you'd be stuck with whatever tip tt put on...
Never know, though, between that and ldrago destroy, who knows what'll happen.
Also, I do wonder why TT don't make different ldrago generations cw's interchangeable. But eh.
