The element thing is a good point, hadn't thought of that. If they removed elemental damage from the stock crucible weapons and made them better for crucible than for PvE (high impact/stability guns with poor mag sizes possibly), that would give people an incentive to do the crucible to get those weapons and have more of an edge in crucible than just walking in with a PvE-oriented weapon (think Thorn vs. a stock, no element HC with max Impact. 2-shot vs. 2-shot, but the crucible HC has the edge because it doesn't need DoT damage to 2-shot. Something like that).
