+330 req for, essentially, free means controlling the map in the early game is essentially worthless. Combine this with the large refund rate, it's almost impossible not to "spam" units.
Given the change to power generators awhile back, the requisition rate should have also come down. This change will also serve to encourage more careful use of units in the early game, and therefore promote more of that skirmish vibe found in Dawn of War 1 and Dawn of War 2.
Additionally, the jump in power income between escalation phases 1 and 2 is too large, it should be balanced out more.
I would like to see the base income on the HQ reduced to something between 200-250 req, but then give a little more +req income on the requisition generators (Which are basically worthless to have, unless you manage to keep a lot alive for like 25 minutes). This change will also serve to make economy harass more significant (And therefore, reward styles of play other than "run everything into opponent's base"). This is something every top player I've talked to noted - that you cannot get ahead of your opponent in any significant manner except for playing the meta (that "run as many units as possible down the middle"). And so, we have this meta that is essentially a back and forth slug-fest with units reinforcing anywhere they please. The game needs to promote strategic diversity (and therefore, reduce this overbearing meta seen in DoW3 since release).
I like Relic's games where you have a solid base income - but this income is too powerful to the exclusion of going for early game "macro" builds.
