Suggestion:
In the auction room there should be a box "Show Owned Heroes" perhaps default checked ON. It would be nice to be able to turn the owned heroes off sometimes.

Years ago I played this and the pets would fairly regularly gain an ability. Now it is really broken. Too bad. :(
Gaining an ability for your pet is far too rare.

There should be a higher likelihood of pets gaining the special abilities. Also they should possibly be able to upgrade their current special abilities. Too often I level up a pet and even at lvl 40 they have gained no additional ability.
