I purchased the Warhero schematics off the pvp armor but wanted to know where to buy the individual pvp mods for the slots; armor, mod, enahncements with the expertise ratings. I haven't been able to find these on a PvP vendor.

Any suggestions?

Do I buy the armor items off the pvp warhero vendor, pop them out then place them in the new crafted armor?

Thanks!

They can be all found in same area, so keep looking. There are different warhero schematics available ( ranked, elite, etc)

Also you need enough valor - i missed that - i've bought all gear thru comms as you need lvl 70 valor to craft:(
