I've been running clones from the start, I've tried a lot of combos in arena and I never dropped as fast as when I left plo in for a day or 2. He's a good character but he takes up a precious slot on a team that needs every synergy point or weakness covered it can, if you don't use the slot for a clone you'd better use it for someone to protect them, that's RG, ST Han, or Sun Fac, anyone else it's too easy to focus echo and sarge and then you're pretty Much toast. Unless your 5s has 80k hp and crits for 7000 on counter ;) mine can solo the first 5 nodes of GW XD
