Guild Wars 2

Hey guys, just wanted some advice on my grenade/bomb hybrid build that I use for general pve and fractals/dungeons and whatnot. Here’s the link:

30/10/0/20/10.
Soldier’s gear
Rampager’s Pistol/Shield
zerker accessories
Ruby Orbs and Sigil of Earth/Corruption.

I was thinking of moving the 10 in firearms to tools for Scope for a dps boost (maybe? I’d lose 100 prec and condi damage, gain 10% crit damage but most of the time gain the crit chance % back with the trait). Also was thinking of moving the 10 in firearms to Inventions for Cloaking Device for wvw.

Are there any good wvw power/condition hybrid builds out there? I’m thinking rifle/grenades? I’m getting sick of the flamethrower and its instant-death against people with retaliation, but I wanna keep my rampager’s gear lol. I kinda realized I probably should’ve gone with Soldier’s gear but I’m too poor to afford that lol.
