Suggestion: PvP defense stats

Would be good to have some info somewhere on how often your character wins/loses PvP defences. Rather meaningless info yes, but would be interesting to see. I guess it might also encourag upgrading of minions (right now I barely care about minions - the only utility that is seen is opening chests and upgrading has such a minimal impact on the time taken that I don’t feel invested in upgrading them beyond watching numbers go up!
