So in summary, and to that I agree I wholly to most points (succinct version…)
IB drakegun/flamethrower is where it should be but maybe a bit too good staggering elites - and only works well with a party that “accepts” it and mostly works around it by having “jobs” that complement each other. So pre built teams and voice comms (which normally is superior anyways…) is the best scenario for any party with an IB drakegun.
If thats the synopsis, then I agree 100% on all main points. The rest is quibble.
