I also noticed another (niche) issue in the Deathlok PvP. I had him on a team with Apocalypse and Scorpion. I used Scorpion's purple to down an enemy. This should mean that I regain purple AP after downing the enemy, but I did not. I presume that the additional damage due to Deathlok's focus points means that there's some issue whereby the game thinks it's Deathlok's power that is downing the enemy rather than Scorpion's.
I split this into its own thread so it can be addressed independently
