being able to sell gear directly off a champ wud be very helpful, wud save loseing it in storage and thats assumeing u have space to even take it off, which i very rarely do

Damage logs and DM to atleast Clans. I like to parse my information after a battle. 

Damage logs in what battles? How do you see this feature working beyond the damage recap screen we have after fights currently?

Damage logs in both clan bosses can be improved, first off the same ability to view damage log later on after hitting the regular clan boss, but what could be added is details on damage.

On each champ you can check how much damage was from toxic set for example, direct damage, war master, hp burn, reflect...details like these would be interesting to know.

Id love to be able to "save" builds so I could just instantly regear a champ.

Another thing that the logs can help with is seeing what you beat a stage previously with. Like there are so many floors and rooms in like Doom Tower/Cursed City/Dungeons etc that I'm like wait what setup was I using for X floor when I had changed it to another for something specific days before.
