If you can make it work with justifiable trait/utility/gear/weapon choices it’s viable. That’s the beauty of the Engineer.
Try everything. All the kits, all the weapons, all the skills. Then when you have favourites, try them all again anyway. I’ve gone from “I’ll never use turrets” to full turret engineer, then “I’ll never use kits” to full kits, then “wth are rocket boots even for, this is stupid” to rocket boots always on my skill bar… Engineers are all about experimentation and adaptability. Try it all until you find what fits!
