You might also consider re-specing your Fist/Cage.I rarely use Cage's Black unless it's as a finishing move because you want to get to 12 black so Fist gets his Purple damage. So I think it's better to run him at 5/5/3 so Yellow is your big nuke and you get the max protect tile.Fist is fine at 3/5/5 where you have him but I've also run him at 4/5/4 so I get an extra strike tile at the trade off of a weaker attack tile. It's a matter of choice based on how often you manage to fire Green.KGB
Made a run at Chrome Dome PvP event. Was ranked #1 a couple times. Last few hours I spent in the teens trying to push up. Got as high as #6. 4 points from the top 5 at 852. Had been up to 917 earlier but the top moved a lot. With 8 minutes left, at 852 points, I won a 52 point battle then won a 54 point battle with 8 seconds left. Final score was 662. So I basically lost 296 points in the last 8 minutes while I was trying to reach the top 5. 296. Oy gevalt.
Just put up a 3 hour shield to save all the headaches and protect your placement.
So in the current PvE, with Polaris boosted, are you using her in the pick 2 and 3 portions? I noticed in my SCL she is dominant. In my PvP she is everywhere and really hard to counter, but that is another matter.
