100% agreement with the original post on this one.

The combination of the weapon scaling AND the Strength scaling for 2H weapon users makes using them in conjunction with Strong, AoE, and undercosted Warfare skills too strong. In particular, Battering Ram, Crippling Strike, and Rage are all very overwhelming for this archetype, are much better than the options other weapons (wands/bows/spears, etc.) have, and are available right from the start! These combined with Warlord means the warrior can finish the entire fight once it reaches his turn. They are literally that strong.
Compared to a standard attack, Battering Ram does more damage, at half the cost, to multiple enemies, and knocks them down! So powerful. The opponents aren't strong enough to pose a challenge, and other playstyles aren't close to on par.
That being said, I think extra combat points spent in the Warfare skill itself are directly inferior to the strength of the 2H weapon skill, only the abilities themselves are too strong. In fact, the Warfare passive only boosts damage to armor, by less (in most cases) than the weapon skill boosts ALL damage, making points spent in Warfare very underwhelming.

TL/DR, Warfare abilities are too strong, right from the start, when used with a 2-hander especially.
