The only problem with Archery is that it is hit and miss (pun intended) on the FPS with sieges. Some sieges I'll have a good FPS and ping and I can hit my target. Other times it's like watching someone run in a dark room with a strobe light. There's one... aim... blip.... he's there... change aim... blip.. oh shit he's on me.... blip...

Like Arkh said, I think the heals, haste and a 2H melee should be first on the list. And I also think people need to focus more on their transfer spells. I know some vets who still have under 50. 75+ heal transfer will get you upwards of 40 hp recovery with a R0 staff. And encumbrance doesn't factor in with the transfer spells, so you can use it with heavy armor.

Archery is good, but I prefer it with small encounters. I find it rather useless in the big ones.
