Yeah, definitely play around with the amounts of mods. Whatever you are facing in arena, you can adjust your relative amounts of health/protection for.
One very amazing thing you can do with a droid team is to adjust droid speed. By adjusting speed, you can adjust attack order, to optimize against certain teams. You can get HK to go before 88, to buff his AOE. You can get 86 to go last to give a chance to recharge HK or 88. Or you can get all your droids to fill TM at the same time, if you are fighting a Rex team or a Ben team with a fast ST Han.
