I would freaking love an option do LIVE duel people by choice, I.E. faction members to test my skills against different players and decks. I mean in a live duel enviroment not surging against their decks.
I would love to see a Diamond Rank in arena so I have a reason to play there. Something really high like 10k add in degradation over time so we have to keep playing to maintain 10k rating then give us a small reward per week, like 2 crystals, for being at that rank.
Can we get away to track everyone's damage dealt and damage received at the very least within our own factions. It would make Identifying who needs more help a lot simpler.
