but needing 80 seconds on a paid ability I believe hinders the unit far too much.
That is a much valid point; the change of timing & cost was a bit too much of a kneejerk response back then when the unit was nerfed. A change in rotation will also not result in the unit being used as infantry crusher, which is massively exaggerated, and numerous points are ignored which result in invalid arguments or points vacuum/excel sheets treatments (furthermore, the M10 which the changes are compared to, had crews, which helped to quickly repair on the field to aggressively pursue infantry crushing. USF also had other differences, which are ignored or falsified). Also I suspect that people in the thread are residing too much on the usual "why is this allies unit buffed, but not my axis unit" line of thought. Furthermore, the traditional quarrel between a couple of users is overly tiring.
I'd support all the changes for the next mod patch [Fall release?]
