What's the point of Wave Sweeper at all? It's obsoleted by March Song.
Not having to reapply it. The benefit of having +16% movement speed + overture/vivace in battle.
Most parties won't even allow you to keep March Song 24/7 without being overwritten by a buff song.
It's also lovely that it works even when off battle, you save small steps that adds up. And the best part is that it TAKES up a falias treasure slot, so there's no downside to having one equipped aside repair cost. No need to replace your armor, shoes, etc. with the Falias Treasure. The only thing you have to worry about is having 1/4 of your Falias Slot taken up, but when compared to the other slots which requires you to be transformed to benefit from, the 24/7 non-trans requirement of the Falias Treausre is pretty nice.
It's even more apparent when you get hit that the sweeper doesn't get chosen for dura reduction, so you're basically using dura over time as oppose to losing dura in combat.
The only true complaint would be the price to obtain it from the player market or the mini game. But if it were sold cheap in npc shop, and repaired cheap (like 1g per point and it consumes 1 dura every 2-3 days), I am sure a large amount of people would choose to have it equipped since it doesn't obstruct anything.
