Rapid Fire doesn't kill faster than Fire/Ice. When my ship breaks I use Air Strike + Burst Fire mostly, but I still use Fire/Ice on mobs. Fire/Ice outdamages Burst Fire on mobs. Rapid Fire is barely 50% stronger than Burst Fire when spamming; Maxed Elemental Boost increases the damage of Fire/Ice by 150%.
I never use Rapid Fire when training because you can't use it in midair, and jump/recoiling while using Burst Fire is far superior to walk-RFing, especially when you have less than 110% speed (can't Dash while RF-ing obviously). Also I might actually need to expand my inventory to hold bullets. Right now I get by with 7 sets, which lasts over 4 hours.
So I think it's mostly between MW and Boost. How much of a difference does MW make when soloing?
