For sword and shield, your warrior can have a long sword, a hand axe, or a mace.
For 2H, the great sword, the maul, or the battle axe.
Are there situations where a mace is better than a sword? Or a maul better than a great sword, etc.? Or should you be looking purely at the DPS stat? I ask because I just got the "Masterwork Wave Blade" schematic and I find that the weapon produced has less DPS than the Tier 2 sword and shield axe schematic I previously purchased at Val Royeaux.
If it's all just a matter of DPS, than there are plenty of same tier schematics you'll end up ignoring since they have a smaller "damage" slot in the schematic.
W&S or 2H weapon choice, assuming the same stats and attributes, only matters in these three small ways: 1) the animation for auto-attacks are different, 2) the selection of upgrades is different, 3) for auto-attacks only, the rate of hits and attack routines are different (related to #1).
Some auto-attack routine details are here (open the Autoattacks section):
http://forum.bioware...mbat-mechanics/For the same tier/level limitation, axes tend to have the higher base damage over the other two W&S options and mauls have the higher base damage over the other 2H options.
For the rest, I agree with Gya. DPS is just an approximation and only applies to auto-attacks. I generally ignore it and look at base damage and other attributes. Base damage, Attack%, Utility that gives Attack% (like Strength for a Warrior), Rune, special effects and Crit Chance/Crit Damage are the most important contributors to ability damage. All else being equal, the more Utility and Attack slots the weapon has, the better.
