For the 2H buff, I think 2H is already too strong. The comparison between 1H+Shield and 2H is just obnoxious, 2H is way stronger. The damage disparity doesn't acquire for the lost of defenses, meaning the critical hit (which isn't too hard to obtain on higher levels) is strong enough to almost one shot everything. Heck, it even makes scoundrels seem weak.
