I propose a champion with unique method of growth
It doesn’t really matter which character it is specifically, it can be an existing one, it can be a Kabam original, but I think it’s about time we see a champion put into the game that is meta and super F2P friendly. We see this in place in many other mobile games, one example that comes to mind is Sharon Rogers from NetMarble’s Marvel Future Fight, she’s one of the strongest characters in that game and she’s obtainable completely for free and can be maxed out completely for free.
So here’s the idea, a champion whose utility is designed specifically for excelling in permanent challenging content such as RoL, LoL, AoL, and the recent Thronebreaker’s Gauntlet, and this champion will be given to all players as a 1-star once reaching a certain milestone (clear Act 1 of Book 1, or something idk). This champion will be the only one in the game with the ability to increase in tier from 1-star to 2-star, etc, and will have unique rank up materials different from the catalysts we use for all other champions. Remember the friendly Symbiote we got during that one event everyone loved? Similar to that but not the same, and permanent rather than for the one update. I don’t want this champion to simply be an easy mode for all the hard content, but maybe something that just makes all this content a bit more accessible to players with skills but lackluster rosters, you can even put the tier-up materials behind certain story milestones to ensure that the champ doesn’t become more powerful than when you guys intend on then being used. Maybe give them certain synergy partners that give them different utilities so that you can rely on them to do the bulk of the work for each path so long as you plan accordingly. Like a Swiss Army knife version of Aegon, who currently fills this role, but doesn’t grace everyone’s roster.
TL;DR - F2P champ that has an Aegon-adjacent part in the meta, so that the only limitation for hard content is skills, not roster.
