You seem like a newer player interested in the game, but you also have some flawed and recalcitrant positions throughout this thread, like this one.
You seem like a person who makes snap judgments and then attributes flawed opinions to people based on that judgment, like you did in this post. You also seem like you don't quite know the meaning of recalcitrant. What is your threshold for progressing from "newer player?" If it's 2000 hours, sure, I'm a newer player.
Unless you are a level one on a class, your offense and sometimes defense is based primarily on abilities in turn based on your base weapon damage. Some would argue it is never smart to use a faster weapon with a lower base damage. For auto-attacks you can attack-cancel to diminish innate attack speed and for abilities, the innate attack speed of weapon types is completely irrelevant. Base weapon damage is king (unless offset by things like crit damage on weapon or masterwork procs). You are gimping your offensive potential on the 2hd warriors if you simply rely on the auto-attack differences between the weapons.
I am well aware of everything you said. Read what I wrote again and consider if anything I said conflicts with what you said. I mentioned nothing about ability damage. I attack-cancel will all weapons and classes. Mauls, regardless of attack-canceling, hit only one target, and suffer from difficult targeting relative to Greatswords/axes. That cannot be changed. Base weapon damage is often offset by other weapon characteristics, which do not always include masterwork characteristics. Would you recommend the Maul of the Dragon over the Sulevin Blade for the Avvar and Reaver? Greatsword of the Dragon? Skywatcher's Cleaver? Edgewise? Swift Greataxe? Those are the two-handed weapons within one level or less of the MotD, which is why I said level being equal, mauls are generally inferior for the Avvar and Katari.
As for your original post on respecs, many players use them. When nightmare difficulty first became I available, I would respec more defensively as well while starting a character off with a more offensive build in lower difficulties. Once you reach a certain comfort level, whether through experience, skill, promotions, etc many longtime players are lazy and no longer feel the need to bother respec-ing.
As in the OP, I welcome your respec builds in this thread. Also as in the OP, I am only advocating this approach for certain subgroups of players, not all players all the time. The qualifiers for the build progressions I suggested as examples of this approach are in the OP.
