It's just nice to have different enemies to play with. When all you fight is Stumps and the Tormenta gang, it was great to fight something different.
I didn't think the skelly ships were to bad, but I'm lvl 38. used the staff (wither) until everything was dead. Staff makes quick work of it, no respawns. The Blood Scourge was a little difficult. On one of them I had 8 enemies using doll on me. Good thing I had a healer with me. Took everything they could do to keep me alive and I had use a tonic too.
Love the new undeads. A couple of them took some time to kill. The respawn fast too. Hope they put them all over the new islands. Soldiers and undead, like in Padres cave. Makes for great fun shooting fire at them with a staff.
