I assume everyone except Herc is on the table. Maybe these guys will get a release with this year's banquet box
Cosmic ghost rider probably staying 6* locked, same with Ronan
Quake and Herc are the only two. They'll have to be remade like magik was if they want to make them available as 6 and 7*.
I do expect any remaining locked 6*s to be released but behind a pay wall imo.
For Hercules;
If they remove "pause death immunity while hitting opponent" and make it "he activates death immunity for X seconds" like Serpent, he can be released as 7 star, he won't be that OP, considering we have Torch, Hulkling, Tigra, Onslaught as 7*s in this game.
Atm the duds are 6* locked. Like Drax geoot and others. They need tuneups which are happening but are limited with time.
I r4d unstopable Colossus and immortal iron fist. They aren't coming anytime soon.
And I'm not interested in upgrading groot and draxes. I will upgrade them with overflowing expiring items, but willingly I have to draw a line somewhere....
Time will tell how many points are needed to cross thresholds.
Magik was 6 5 star locked until recently. Who is to say that Quake won't be given similar treatment next year? It wouldn't take much to un-break her / allow her to be released if people valued getting 99% of her kit / losing the 1%… but People are "afraid to change her". Just update her kit to require a refresh timer in between auto-evades.
