well as I said.. with it.. they'd have to work on the balancing.. and also.. atleast with flipmax half of the attack is the heat damage you do to your opponent etc... which you wouldn't get from a medic drone etc...
I forgot to take in account heat damage...( been gone a while). Still, not every drone can overheat opponents though. If a medic drone were to be used, maybe make it use heat and/or electricity to power it up? Of course, the amount used would be up to the SM team. Plus this is still in beta... They could easily take an item out of the game if they really wanted to if it was not working out that well at all.
I would not mind a medic drone to much, I just think it would be difficult to balance. If anything, make it heal half the damage that is done to an opponent at least. That way, it wont be an unstoppable mech with high defense that won't die.
