Questions about the game

Hi all,
Started playing a few days ago, read the help/faqs and what posts I could find here.
I have a few questions, here they are:
1 - Weapons are strange, some seem increadibly good, others incredibly bad. Are dmg ranges just an aproximation, ie a moderate-heavy can be like 10-15% dmg, while another moderate-heavy could be like 8-18% dmg?
So far it seems like the 3/2 Battle Blades are very overpowered, the same being true for some other weapons.
2 - Any maths for the game, regarding how much stats/skills affect each actions, etc?
3 - Are there any modifiers from the alt mode, appart from the tactics that can be learned? Like Helicopter, Insect are exactly the same, but Airplane just seems better...
Thanks in advance.
