Well, paladins get to play with Stoneskin instead of Second Wind. And looking at both, Stoneskin can cone on top by the fact that it has no CD and can be used on others.

Surely the downside is it is not instant like Second Wind.

Also 1handed/2handed weapons don't affect the potency of attacks. If you give plds and wars the same ilvl weapon and the same amount of str without extra buffs, their hits will donde the same damage.
