IF you mean C as in classic then you're outdated
. The arena in ladder slasher is gone and I don't think it's coming back.
As in zealer paladin. If you have enough quickdraw I suppose you could really get a lot of extra hits in but you would have to sacrifice stats and damage overall for it. Maybe you'd want to do that on samurai or monk instead of paladin tbh.
Best weapon for paladin is probably axe because it crits very frequently in relation to the other weapons and it scales nicely with the paladin's base stats.
