How many times I have already beaten a challenger on the challenge page, if having per pet is confusing, then total wins.

Armory, scroll, and equipment mass adding / removing

Stats of the enemy dynamically change when I select different pets. If I have 50 wins vs Saggitarius I'd like to see the updated stats.

If something is "disabled" vs an opponent I would like to be able to know that on the challenge screen Just a simple tiny icon would suffice Cant freeze, cant steal, cant blessing etc

"Categories" between the different challenge levels. More easily be able to distinguish between the difficulties

Ability to "Favorite" challengers so they appear at the top of the page.

Descriptions of what weapons actually do in the item page and armory page.

"Heal All" on the healer page.

I would also like a better way to track your wins against certain challengers, I went through a battle phase some time ago and it got annoying having to look at the individual records to see if it was worth continuing to fight certain challengers or not since they give out less EXP after a certain number.

The mass add/remove would also be very useful, as well as a better way to sort out the items, and an option to display them in different orders.

I would like a 'Are you sure you want to remove this item from your Armory?' prompt on modify weapon set page. There is a checkbox to deselect the weapon from the set but I clicked remove and it obviously removed it from my armory, I think removing the mod crystal that was on it. Would be nice to have a failsafe for idiots like me!
