I wish i could help you but Ubisoft ban my account for cheating which i did not. What level are you right now?
Tips
from lvl 1- 30 don't craft items, save those crafting materials
don't do hard missions when soloing and try asking for help there are some people who will help you do mission
Complete all side mission, it will help unlock skills like first aid and stuffs
don't go to DZ unless your lvl 30 but i would suggest getting a good 256 gear first before doing any pvp
always use cover
as much as possible don't sell stuff deconstruct them
try using a weapon with these weapon talent brutal, responsive, deadly
