Love it. I wish there were more ways to increase the awesomeness of the bow though. Oh and back up auto shooting archers and minions like the gargoyle.
Great game, but a filter for the students is needed. Too troublesome to navigate for questing when you have 10+. I also have 1 group of questers that I want to always be on the top 4, since they're the only ones i take on non-dispatch quests.
A full int ranger can substitute for a 2nd healer, especially with nature's balm. He can be a stunner and poisoner when no one needs healing. Try maximizing the buffs. They last the whole survival game once applied. (same goes for curses and debuffs, unfortunately). Having a back up resurrect is handy in case you get unlucky and had your cleric killed. Don't be ashamed to go slow, rushing into the next wave can cause you some... problems. There are lots more for tips but I advise just searching the forums.
