1.Your unit placement and combination matters a lot, since everyone has different strategies and units on the battlefield. You have lots of different and unique units to unlock and level up. I enjoy the PVP aspect a lot, and I hope it will be easier to gain gold and units in the future. (Recent Patch increased your unit levels to from 15 to 150. Idea is great, but right now you need more gold to upgrade your units and it is really tiresome and time consuming, this is why I give 3/5 rating)
