mid-edit while you posted up.
IMO this is an important topic for Marvel. The older the game gets, the more great players will gravitate towards low-tier, if only for laughs/rekindling interest/new set of challenges… etc.
Even if/when Low Tier gets established as a tournament event, the rules could vary from place to place (and should IMO, perhaps with the exception of Evo where money on the line makes a concrete Rule-set damn necessary). Having to adapt your team and strategy from event to event would reward the great players and keep it fresh.
My only real gripe with a system that allows Tron, but straight-out bans, Blackheart, Spiral, Strider is that it’s effectively supporting a rush-centric playstyle, and banning a lock-down style.
This is just a sketch, but I’m saying let people pick the lock-down characters, but make them conform to a point system when it comes to assist selection. Something that bans projectile assists, Doom AA, anything that gets you control of the horizontals, etc. so that now you’ve forced gaps into trap patterns.
I’m all for a system that bans the absolute minimum of characters, even if it means adding in place handicaps on specific characters-- simply because even though on paper Dhalsim/Blackheart/Spiral/Strider/Doom/Cyke stand up to God-tier, in tournament play, they still rarely do, or are even used for that matter. So having a tournament that lets you pick mid-tiers is sounding good too, if it can be balanced out.
