The worst feeling with the required three cartridges is in dungeons tbh. In ShB you could burn all the gauge you wanted in a mob pull, Gnashing Fang Combo'd the last few adds down, jump right into the boss, 1-2-3 > burst. Can't do that anymore. Can't Gnashing Fang combo the last few mobs unless you've already pocketed two cartridges so you don't ruin/delay your burst on the boss. Holding onto cartridges in EW you could have spent burning down mobs faster like you could have in Shb just feels awful.

I like the idea of Double Down being one gauge, bumping the required to two(hell, DRK gets their 90 abilities for free). I completely understand the want of a longer NM to fit everything in, but tbh I dont know if I want a 25sec NM. If anything 21sec max to squeeze in the Hypervelocity. Adding more time to our already long window doesn't sit as well with me.
