USF do no have impressive off map? seriously? The IR pathfinders is almost certain hit to any unit that can not retreat, The time on target does significant damage to OKW trucks, M83 cluster mines wipes out ATGs, White phosphorus force retreats and leave unit healing for a very long time.
For someone so keen on pointing out the smallest of details, you might want to read the part where I said they don't have that many, which doesn't mean they don't have any. Time On Target currently doesn't even guarantee to destroy a howitzer and dealing some damage to OKW trucks isn't a quantification of "impressive" in my opinion.
If you want to make it a "stock rocket artillery equivalent" move it to major re-balance/redesign it and make Scott doctrinal.
And again I literally gave you the reason why I think the way I think, which is that Relic will not allow major redesigns at this point. So what you are suggesting is pointless. We have to work with what we've got and that requires some units to perform as crutch units, because the USF still lacks certain stock options and we can't "simply" go around nerfing all of them without risking to ruin the faction. Changes to these crutch units (which I do think are necessary) have to be small and very well considered.
