For single target, something like this waronlinebuilder.org - Engineer buildOsred wrote:For someone whos just entered T4. Whats a decent spec to use where you wont feel entirely useless.
The last 2 point you can play around with. Either get utility in Tinkerer or just level Rifleman to get more damage out of your main dots.
It is a very noob friendly build that give solid single target damage + it is somewhat forgiving with the healing keg. Should let you get a fair share of kill quite easily in keep siege while staying mostly out of harms way. Snipes 150 feet range is really good to finish people off in siege defense. And basically every Morale 2 (every minute or so) should let you get a kill using your 2 main dots : Signal flare and Incendiary rounds + Focus fire.
Target squishy like sorc, SH, WE, choppa... Leave the tanks alone.
