When this game starts releasing more 4 star heroes and there is an abundance of 4 star heroes will the 3 star heroes become useless and gather dust?
I think to avoid this they should allow only one 4 star hero on each team. also, there should be bonuses when you pair up certain heroes. For example if you pair Invisible Woman with lets say Mr Fantastic you get +5% health just as an example!
Maxing out a 4-star probably requires a thousand dollars or a year of dedicated time.
The 4* characters will dominate the game in much the same way as ultra-luxury cars dominate the highways.
One thing they should work about one day is the huge gap between stars in this game. It has serious balance issues and i think their stars mechanics are part of it.
I would have cap heroes in tighter way, 50-75-100-150 or something similar but not as huge as 55 levels between two different stars.
Now interesting one star heroes are crap, 3* ones are way too powerful. Terrible balance i think.
Talk about creating something out of thin air to worry about. With only 2 4*'s out there, and only a small fraction of the playerbase having all their covers for them, this is going to be a non-issue for almost the entire lifetime of this game.
Also, think about how your current roster works. I have 3x 3*'s over level 100 and I still usually have a 2* in my team a lot of the time. Heck, for this last PVE, I was using the boosted 2*'s almost every match (specifically CStorm and Mags MN).
