PGL is a lot of fun and if you practice the Pounce > Sucker Punch combo you should never run out of MP while solo. You can time running through the enemy for pounce or just wait until you land the stun from Haymaker if you can't get the timing down. Just make sure to put your weapons away when you aren't actually fighting.

Truth be told, though, I found all the classes surprisingly fun pre-patch and even moreso now.
