I know the game is very new and some really great iconic characters have come out.
I don't think us, as players, need a lot more power except we aren't sure how hard Galactic Wars is yet with the change, time will tell.
I'm sure this has been brought up before but, what if you could create your own character and give them abilities from a certain pool given. As well tags, classes, or races.
For example, you'd start out and pick Light or Dark, then pick your species
Then you'd your tag/specialty/whatever you want to call it
Then you would pick your class
Lastly, you'd pick from a pool of abilities that are standardized across the board.
Perhaps have certain ones unlock from different missions, or be purchasable through gems, cantina gems, GW gems, Arena points etc.
To expand, maybe have "mentors".
These would be NPCs like, Darth Vader, whom you can learn Force Crush from at a cost and if you pass a certain kind of trial.
This would make the game diverse, and have our own personal lovable squishy or not so squishy person that we can use to benefit our own success and build upon synergies!
There could be a cost to "reroll" your character's class race role etc. with Crystals or something.
That way while building your almost "perfect" team, your avatar person can be the last piece, or the first, to build your team around or with.
