It's best to see how it plays out with more players and updates. The direction of OHD core sounds like it is toward larger maps, combined arms, and a situation where you just aren't spaming them at tightly grouped infantry as you may be imagining.
Consider that mechanics such as arming distance, firing delay, etc (not necessarily, just off hand examples) could be used to make the weapon less of a "noob tube" and more toward a situational utility, both taking out vehicles and infantry that is dug in.
