I'd like to see repair costs regulated, or even lowered.
Auto-balancing still feels broken, one team tends to dominate for all of the rounds after round one. Perhaps, if possible, make it based on someone's K/D ratio?
More info about retiring would be nice, as I understand it there is no longer a bonus to WPF? Not much incentive to get up to 30, retire for an heirloom, and restart just because it will be faster the next time. There may be something I'm not aware of there, however.
And finally, getting slaughtered by a charger that's just galloping around isn't a particularly enjoyable experience. I'd like to see the damage lowered or a penalty for the horse and rider. Perhaps the horse stopping or slowing significantly afterward and a longer time to get going again.
