If you're a pure paladin and you're not a high AC build (by this I mean over 50 w/o buffs), is there any reason to go sword and board after about L10? I have a nearly capped pure paladin and I've always been sword and board (won't go TWF as feat costs are too high). I'm not sure I have the strength to make a two handed weapon build worthwhile, but I'm really not sure that sword and board provides me anything useful anymore beyond occasionally blocking. Should a high level pure pally, non-AC build, start looking to switch from Longsword or Khopesh to TH weapons? If so, which one?
