Vipper is right on that one. The reload does not matter as much because wind up/down times contribute a large chunk of the delays.
The PM71 should have a ROF of about 7.3 secs, the GRW of 5.9 (my calcs). I think MMX's simulation is probably the best reference for mortar performance since it takes scatter into account.
I suggested as compensation -1,5 sec reload speed. Look at my first post.
Jaeger Armor Doctrine is too potent in team games.
Combination Elephant + spoting scope + recon overflight + AT strafe is so good. This commander is picket 2x more, then second one and overshadow all others commanders.
