Isn't this basically a player falling into a "trap" by picking an unoptimal choice simply because he modeled what was on the sprue? Like giving wyld runner a whip, one of the worst melee weapons in the game that locks you in S2, because you've modeled her that way. If we consolidated weapon options and make each weapon properly priced/fill a niche, players could model whatever they wanted and not be at a disadvantage.You misread me. My point is that you, as a player, can disregard the weapons you don't like. Someone else, with different preferences, might still want to use them.
If someone wants to model something unoptimal just because it looks cool, I don't mind. Hell, I regularly run Krumper as goliaths (imagine a bolter with a 9" long range) just because I find the idea of enemies getting pinned to a wall by a salvo of sizzling rivets to be absolutely hilarious. But I'd prefer for all weapons to have a place in the game and have a reason to be picked other than the model/weapon bit itself looking cool.
