I was basically thinking to switch the damage bonus commando has to assault and vice versa (most of it). This came up with the reasoning that damage bonus is related on finishing a fight as fast as possible related to the assault fragile philosophy compared to comando which has more resilence for its passive EHP that prefering sustaned fight bonus adding a support bonus, related to AV. The idea comes as follows:

Commando:
General bonus > 2% damage bonus against vehicles.
-Caldari > 5% bunus reduction to kick and charge time on hybrid-rail weaponry per level
-Gallente > 5% bonus reduction to dispertion and reload speed on hybrid-plasma weaponry per level
-Minmatar > 5% bonus to projetile clip size and +1 explosive clip size per level
-Amarr > 5% bonus to heat reduction of laser weaponry per level

Assault:
General Bonus > 5% to reload speed on weponry (instead of the CPU/PG reduction)
-Caldari > 2% damage bunus on hybrid-rail weaponry per level
-Gallente > 2% damage bonus on hybrid-plasma weaponry per level
-Minmatar > 2% bonus to projetile weaponry per level
-Amarr > 2% damage bonus on laser weaponry per level

Basically u can notice that bonuses could apply to light and sidearm weaponry on both cases.
Also this leads to a possible food chain:
Assault (better chance to deal with heavies with their damage bonus to mitigate heavies damage reduction) > Sentinel (better way to deal with scout sorprise attacks with its resistance and EHP) > Scout (better dealing with assaults low health)
Then Logi and Commando would fill 2 necesary support roles, supply/repair/spawn logi and self sufficent AV commando.

The reasoning behind this post is to try give the role assaults should have had since the beggining of uprising from my point of vew (been here since beta chromosome).
This is considering Charlie.
Please keep it constructive and sorry for the mispelling of some words, english is not my native language.

I know it changes the roles we use to have like commando minmatar and amarr assault, but this came up with the addition of a food chain mechanic and an overall balance for the game (in my opinion of course) cus it would give more coherence to mechanics and a more defined role for assaults/commando, of course , all this is to give an idea of how to give fulfilling roles and subject to change in order to fulfill such roles in the best of ways. About the suppression i think that should be an assault machanic but thats just me i guess.
