Yeah, I agree with the other people who have spoken already about ramping up exposure now that Apex is over. I do think it's important NOT to tout the custom moveset project as a "solution" to campy play. I don't think there's a consensus on whether custom moves as a whole will shift the aggressive/defensive line in either direction yet, so we shouldn't be making any promises. After all, the real root of the campy play issue lies more in game mechanics rather than character moves (no matter how much people blame dabuz's Rosalina). I think it's better to shout the praises of just how much variety it'll bring to casual and competitive play. Dynamic and unique matchups are inherently more fun to watch than the same 5 characters beating on each other all the time.
It's quite important to note that, in most cases, defense and offense are not really specific to a move (as in no single move makes a character or game defensive or aggressive), but are rather results of a character's kit. It's very rare, for a custom move, or several custom moves at once, to change a character's over-all playstyle so drastically (Palutena being an outlier, due to Lightweight and Superspeed) as to reclassify their playstyle from one lean to another. It's important to market customs as what they are: both an additional layer to the meta-game knowledge of matchups and options, and an in-match way of tweaking characters to suit scenarios better.
There's no guarantee they'd make the game faster, or more aggressive, on the whole. But there
is evidence suggesting that they make
many characters more versatile or viable, and in a lot of cases, in ways these characters really need in order to keep up. There's some room for preference - to my knowledge none of these is
objectively a pure upgrade, though many are
subjectively vast improvements (such as Power Vision) when used skillfully and in appropriate doses. What that tends to indicate, especially with a lot of top picks wanting 0-1 customs in their arsenal, is that these moves
do improve balance over-all, and offer more dynamic play.
The big hope for Online Tournament Mode is that there will be some way... ANY way to ensure (short of invitational and honor-bound player pools) that Custom Equipment is off while Custom Moves are on. While they're bound to the same system, there is always potential for a player to subtly (and unless they tweak things, untraceably) cheat on any online customs event.
