First of all, similar weapons have different costs. Why in the world would anyone buy a greatsword when they could get a maul for cheaper?
Second of all, the greataxe is useless. Look at it. 1d12. The maul and greatsword (which are otherwise similar to the greataxe) have 2d6. Just think about that for a second. The greataxe can deal 1-12 damage. The maul can deal 2-12 damage. In fact, if you do the math, 2d6 averages one point higher than 1d12. So why in the world would anyone use the greataxe?
For the people that down't niggle over DPR and drool over optimization options, use what you like. I'm a greataxe wielding barbarian! Fear me!
For the rest, use the thing that will get you another point per hit. I do 18.73 damage every 2.5 rounds! Fear me!
Best of both worlds!
Do all weapons have to be exactly equal? Why can't some be better than others? I'm fine with it. I'm not a fan of balance just for it's own sake - it's a tool, not a goal.
IMHO the problem is that this actually goes against the casual players.
I like making choices based on character image and "style", as casual players often do. I don't like feeling cheated by the game when I do so, and that's how I would feel if I didn't notice that another weapon (or spell, or another choice) was straight better.
Especially when it could have been *EASY* for the designers to fix that! I mean, look at the weapons list in the 3.0 PHB as an example, it was hard to find two weapons one of which was straight better than another, there was nearly always a trade-off.
Two nearly identical weapons are not a problem. If they are truly identical but they have a small price difference, I easily get over it since minute money differences are irrelevant after a level or two, but even in that case I'd be so easy to compensate for instance by making the cheaper weapon a little heavier to carry.
Maybe I am too OCD about details (I do that at work all the time...) but seeing designers being told their details are a little off and not seeing them taking any actions, is what we call sloppy design.
