Just a tip on targeting with the controller... Filters not even needed for this. Hold R2/L2 to ready your crossbar abilities, and then tap R1/L1 to toggle through enemies. This saved me Soooooo much grief, as it will never ever target pikachu! In hectic situation, it will ocasionally target a wrong mob, because your toon will be facing an odd direction. However, it is way way better than relying on the X button alone to try to target whats in front of you, and makes target switching in dungeons a breeze.

Hope this improves your experience as much as it did mine. ^^
