Undo the Bonus Heroes "vaulted" character selection.

You just eliminated the champion system which is awesome, so you can force feed down our throats the latest dozen 4 star characters.
The bonus heroes things is fine
On the other hand the vaulting (putting characters covers in an unreachable vault) hinders the champion system. You have just said, we can not get more 4 star characters except by a stroke of pure luck (5% chance)

If you really want to force feed down our throats the newest four star characters, please just do it for the Legendary Tokens, and allow the full spectrum of picks from the Legendary Classics.
Or heck go vice a versa, (which might avoid a class action lawsuit) and allow the Legendary Tokens to grab any four star from the full spectrum.
At least give us a choice.

Forcing us to choose from a dozen of new four star characters, while ignoring a substantial part of the character pool is unfair.
Many of us spent millions of ISO to champ 4 star characters that we now can not add more 4 star covers to for additional levels, because it's impossible to get those covers, except a super rare chance.
We champed these characters so we did not feel like we are wasting covers, now we essentially wasted millions of ISO.
This also causes an issue with VIP. You see the VIP purchases promises us TWO legendary tokens. These Legendary Tokens are not just a 15% chance for a 5 star, (now 14.25% with a bonus of 0.75%) but they were also an 85% chance to get a four star from your giant pool of four stars.

With out consulting your player base, you have CHANGED what those legendary tokens can purchase.

Please do not do this.
