best mech gun?

[Hrith]

The damage that the Red Mechs does is only barely more than that of the 9000M.

You might wanna recheck that in-game.

The ATP of Yas9k fully ground is 60-100, not 80-100; 80 is the average.

30 ATP on a saber is next to nothing, on a mechgun type, it's a clear advantage.

Not to mention that:
-Red Mechgun has a very good special, Yas9k has none.
-Red Mechgun is a lot easier to find with hit%
-Rifle range on a mechgun is next to useless

And also, it's annoying to switch between the FS and a Demon's weapon all the time in the Tower, especially when the 9000M will take any of those enemies in 2-3 combos (depends on having Zalure/Shifta).

You cannot Zalure a monster at rifle range (except with S-Rank Rifle with Zalure, making you swap weapons anyway), so FS + Demon's Rifle is clearly faster than Yas9k for killing monsters in the only area where rifle range matters: Control Tower.
And if you kill monsters at rifle range with Yas9k without freezing them with FS, you'll miss a lot, since Yasminkov "bullets" are more likely to miss than regular bullets.

Demon's Rifle > Yas9k
FS + Demon's Rifle > FS + Yas9k

In all cases Yas9k loses.

And Gratia only boosts Yas9k ATA (speed boost is useless), making it better in no way.

Guld Milla > Rage de Feu > Mille Marteaux > Red Mechgun > S-Rank Mechgun > Yasminkov 9000M
