Guild Wars 2

hi im doing a warhammer 40k space marine RP in guild wars2 and the closest thing i could find is sword/sword rifle for warrior

Sword/Sword only works with Condition builds which are very impractical for PvE. If you do decide to use a Condition build I’d avoid using Rifle and go for Longbow instead. LB has way more utility over the Rifle with the added benefit of AoE which the Rifle has none.

Heres an example of a Sword/Sword+ Longbow build for PvP/WvW:

You can also try a Hammer build if you want the (Thunder Hammer) look. There are multiple variations, but these two are pretty common:

Hambow (PvP)

Frontline Shout Healer (WvW)

Kesslar, sword/sword rifle for PVE is just fine. You don’t have to be a condi build and since your roleplaying, whatever is fun for you will be better than any build you find here. Personally, a 0/6/4/2/2 build works for me and I have no problems. If you want to get into WvW or PvP, you’ll want a more optimal build.
