Not sure if anyone has noticed this yet, but AP is no longer working. Un-training AP and putting armor onto the minion still gives them the .5% reduction to penalties. Training AP on someone who doesn't have it and putting armor on them does not give them the reduction.
Training exp or equipping and re-equipping armor does not fix it. Not sure if cache flush resets the correct AP status as I haven't tested that.
Lastly, AP is not in the dictionary :(
