It should be noted that a med-bag or defib only pushes you to 12-13k, and opens up additional cash-flow options. Med-bag is best for XP grinding, defib for profit. Still, you are forced to find meds and other utility items in the zone. This is most apparent on Bakarani and Ozeti where you can be stuck in "long" range fights where looting isnt possible; Ive been forced to beg for meds or heals from others simply because I cant access my kills.
Season 1 Vector is insane, so as long as you are the one peaking first even 1vX'ing T4 Armor is more than doable under the right circumstances, thus we are able to take cheaper (and lighter) armor since we can win any 1v1 with raw firerate. Level two armor protects against .50-cal oneshot in chest, the helmet simply makes AP and FMJ do the same damage. Medium tac vest bc small is too limiting. I use orange meds here bc the premium for faster application and full health bar is worth the extra $600. Stims are mandatory.
