Guild Wars 2

for pvp i use rabid based builds with pistol pistol or pistol shield. For pve i play celestial with rifle and berserker rings, amulet and so on. For wvw for now i was playing as for pve but i was thinking about a condi build for wvw similar to the ones i use in pvp. Is condition /power eng good in wvw ? any suggestion about runes and sigils ? The armor in this case should have rabid stats ?

Good builds I think you’d like condi based are:

Rabid armour + weapon, celestial trinkets OR Full rabid (both will work) Weapon I’d use would be p/s.

Nade Kit, Bomb Kit, Elixir Gun or Tool Kit

Run at least two of these kits, nades is most beneficial fro this setup:

I’d recommend Nade + Tool + Elixir (but that’s just me)

Go for a 6/2/0/4/2 setup.
Shrapnel, Grenadier, Incendiary Powder,
Fireforged Trigger,
Invigorating speed, backpack regenerator
Speedy Kits

I do it a bit different. Build editor is down so warning on the format.

I would take p/p initially because burn is super strong (like a Norn’s body odor).
It is also easier to get the hang of.

For kits, if you want conditions you should be using grenades and e-gun (which is super effective for defense and is great 1v1 with weakness restacking). The third kit is really up to your playstyle. I like bombs (go figure I was named for that kit) because you can do so much with it (might, stealth, confusion, immob, smoke etc). It can add a lot of condition pressure, but I am fine if it just is a utility kit while I toss nades!

Forceful explosions is great. Shrapnel is the best if you don’t take bombs, but it isn’t really that special.

Invigorating speed can often be swapped to protection injection. Protection is soo OP.

Sigils:
Energy (need vigor some way)
Torment (great to have even more conditions and this one covers burn)
Battle (you swap so many kits that you should have 6-9 stacks up which is a lot)
Corruption

Others are situational:
With Krait armor take Sigil of Earth (for max out bleeding)
Taking Giver Weapons to get to 90% (look at a sigil of malice that extra 10% is an extra tick for many skills).

RUNES:
Perplexity is great in small battles
Antitoxin is great defense (- condition duration)
Some take Scavaging

Situationally I like Krait as that really can make stacking bleeds very fast.
Aristocracy has value too but it requires YUCKY PvE to acquire.

Might help you out if you have a look at Wolfineer.com. That site is ran by me and has a ton of Engineer related information, it should help you out greatly.
