GMST Class Testing

Other than the request of testing out Grenade and Flamethrower, is there anything that oughht to be tested on a Corsair? I'll be playing that once I get the DC ores for it.

Check Octopus/Gaviota damage.
See if you can find out odds for different dice rolls.
Check damage for Flamethrower without flame capsules.
Check how Element Amplification affects DoT.
Check how Battleship affects stacking with other skills and Hyperbody
Check mechanics of Vengeance.
