There's a pretty big argument to tone down auto-fire, too, for the same reasons. The skill input needs to reflect the return; this is pretty much how all RTS games are balanced.
And yes, the 6RE spam is an edge-case where the player probably needs to improve; but one or two RE-RifleNades supporting a proper rifle push is far too effective for the amount of skill required.
Sorry, but being upset about the micro cost of an RE unit with a grenade after 4 days of seeing them is laughable compared to other axis examples like IRHT combo'd with 1 click rocket arty. Move out of the garrison or kill the RE. It's not hard to do either. Hopefully balance team is much smarter than to remove a new upgrade a week after release because it taxes an axis players micro in an annoying fashion.
Secondly, removing auto-fire from in-direct units is so stupid. They're indirect fire units meant to smash anything that can get spotted for them in range. We've been told to move our units for the last 6 years the games been out to counter IDF, but now I guess the community doesn't want to micro anything?
