Bulwark weapons

At least on rank I its 15-22-30 with 1-2-3 allies near. Dunno about anything else.

Well, so far siphon doesn't seam to improve at all, my siphon ruzad 4 has the same stats as the level 1, as does my zalkin 2.

SO probably 15/22/30

Thanks everyone. Any info on the area of effect?
Btw, it would be nice to have some visual confirmation (like switching on fortification) that the bonus DR works.

I tried the cyclon bulwark and have not seen anything; I will look again more carefully.

There is a mist like visual effect and the range is approximately 5-6 meters.

Camper weapon. Useless.

So you have to literally sit on each other to get the bonus?

In platinum you'll have to do some camping if you want to survive.

I don't really see a point in bulwark if you have siphon, or for some weapons concussive. Health regen is much better in general, and there's a case to be made for concussive if you're using an accurate, headshot-y weapon. Bulwark is useful for camping, and that's all.

Side note: I'm getting pissy about this whole special weapons thing. I'm at Revenant Siphon III, and I still have a number of rare guns beneath that rank in base form. I could get onside with the S weapons, since essentially it allows the Avenger and Co. to be balanced for Gold without making the game too easy for new players, but this new development is just bad. Poorly conceived, poorly executed. At the very least, they should have been locked out of the pool until all base rares were maxed. I understand wanting to give people more stuff to unlock that could potentially help with platinum, but the way it was done was terrible. /rant

edit: I just realized "Understandable, but poorly executed" is basically a short description of Andromeda's development.

for a dedicated gun user siphon all the way (tonsa gun damage and tons a kill steals with said gun - more competition with other siphon and concussive users, krogans, kiteticists, snap freeze engineers and explosive invasion operators) .. For a class that does most of its damage without the gun powers/ combos / melee etc) siphon is pretty useless while bulwark is a passive bonus THAT ALWAYS WORKS regardless of how much you fire your gun (as long as your friends are close enough to offer moral support)..
NOT a primary weapon. Something you can switch to when team is forced together (ex hack/upload circle) .. 

Actually while the damage reduction multiplier has diminishing returns - the amount added to EHP is linear +1 EHP per +1 DR regardless of how much DR you already have .. Good for all and every ..

DR is the gift that keeps on giving. No diminishing returns on effective hitpoints gained whatsoever ..
