LR: Weapon tiers

[Buster TBM]

A long while ago i found on some forum a tier list someone made of all the weapons in the game for the arms.

I do not remember who made it but this is here for the discussions.
i pasted it in my dropbox and put it here for everyone to see.
(Please click download on the site for the full view, this is horribly small)

My question is, do you guys agre with the pic?
and if not, what do you guys find more better or worse weapons?

I think a lot of them are higher or lower than i should be but i could be wrong and this is a perfect tier list.
