Online GM or Online Universe - Yeah GM mode would be cool and all, but excluding an online version would be a missed opportunity. In theory, have up to like 4 or 6 users creating their own show, drafting rosters, booking it, trading wrestlers and whatnot. Goal could be like OG GM mode and strive for higher ratings, or it could tie into the star-rating system.
If no GM mode, just implement these ideas into Universe. I'm dying to book shows with or against my online buddies, but apparently I need to have freakin' NASA's internet to make PS4 shareplay work.
Story Designer - Self explanatory, but also I really miss newlegacyinc storytime .
Significant additions to create-an-arena - More venues, stage parts, etc.. Fixing the bug that causes trons to flicker during caw entrances would be great.
Good netcode - Jesus christ this series has the worst input delay, no other fighting game comes close.
