I've been running the same build since pre EOF which includes a rapid-fire glaive (Backfang) and Lost Signal. Pre EOF I would get 8/9 glaive and 3/4 LS shots per finisher but now it's 4 glaive and 1 LS shot. Pre EOF felt great since it was a meaningful amount of ammo, but not too much. If mismanaged, it was easy to run out. In EOF, DS imposes an additional cost ([u]ammo meter progress is halved[/u] + ammo per special brick halved) and requires an additional investment ([u]200 weapons[/u] + special finisher), but you are not adequately rewarded for that higher investment solely because special finisher bricks, the main source of ammo for these builds, don't get doubled from the weapons stat. All of my double special builds have me constantly low on ammo. I know it's less of an issue when not solo, but not being self sufficient isn't good.
