Switching out some Soldier is always an option -currently every slot has P/V/T which could be overboard. In a zerg just stand back and auto fire and pull then start your burst chain!
The other thing to keep in mind: A lot of times if you get focused your going down, no matter how much vitality/toughness you have, so in zerg fights mobility is more important. I’d recommend taking a more balanced approach on stats. It shouldn’t be too hard to get about 50% crit damage and about 30% crit chance (50% with fury) after a bit of mix and match on gear. Weave in and out for the close range and long range options. The other thing is that builds like this are very good at picking someone out of the crowd.
On runes: thing with an hgh build is that might is THE most important thing to have, even in a power based build like this. With proper runes you’ll be able to keep around 20 stacks of might up easily. Without the other might duration runes you may find it a bit lacking overall. I’d recommend either trying the other 2 might stacking runes (for a total 60% might duration + 30% from traits) or going boon duration with runes of monk and water (Or 4x altruism 2x water if you like that route).
Sigil: There’s some decent options here as well other than force. Number one is Sigil of battle for more might stacking which may not have as much of an immediate effect but long term is much better. It empowers this build to stay close to 25 stacks of might at all times. Other options I like here is Leeching, a very underestimated rune that works as essentially a 1800 swing in your favor. (900 health gained, they loose 900 health)
Food: if you find yourself balancing your stats a bit more I’d try Bowl of Curry Butternut Squash soup for the extra crit damage.
Some other things to consider: Namely traits, As an engineer using toolkit and rifle you’ll find yourself up close and personal very often, however you have a ton of control options. With that in mind I think you could at the very least drop rifled barrels and take go for the eyes instead, or hit up the explosives line for Incendiary powder. Also I dropped Cloaking device a while back with my builds and haven’t turned back, its good but it almost seems like a crutch to me. My personal preference here would be drop rifled barrels and cloaking device and put 20 points in tools for speedy kits and power wrench. this gives you a 20% reduced cooldown on toolbelt skills, 20% reduced cooldown on tool kit skills (Gear shield 20% more often? Yes please) and unlimited swiftness.
Hope that helps, just remember this build has tons of CC which can make 1v1’s a nightmare for other players.
EDIT: regarding PvE, which I forgot mention, this build should have a solid effect in PvE as well. Toolkit allows for some nifty kitting.
