avv is wrong.
carry weight is a major factor in creating builds and in combat as well, and im not just saying that because 90% of my chars are st2 and less. The cw might not be the deciding factor in planning a build, but it surely matters if you are able to carry an rl on top of your burster equipment or if you can carry enough ammo/stims to last in a long fight.
Another factor is looting. As of now, loot is a big strategic factor in tc or battles in general and it should stay that way. We all have experienced it when we waited for the loot to be carried to tents before getting attacked with half ot the fighters in bluesuits, coming back from their tents (though certain gangs have found a failsafe solution for that problem).
There is no way that "cw doesnt matter for pvp" and there is no need to change it.
also, by rendering low ST chars unusable through ST requirements for perks, the specialization of the build system certainly is narrowed.
