False. The slight multiplier advantage 2H weapons have is almost entirely canceled out by their slower speed.
Potential is just gives 1H a bigger edge.

But they have scrolls for Armor for W.Atk, correct?

The problem with your suggestion is that you're cutting out reasons to go 1H instead in an attempt to make 2H viable. That just shifts the problem in the other direction instead of fixing it.

As I've said before, the more obvious solution is to make Paladins use 1H weapons, period, and make Heroes use 2H weapons, period.

There's that much of a gap between speed 6 and speed 5? And by potential, you mean having unnecessary amounts of Str %.
Armor attack scrolls come only from events, and they're far and between.

Why would Heroes use 2h blunt weapons? They don't have blunt weapon mastery.
