Chiming in late to the "The Harvester is OP" chain of discussion.
One other point to make here: Yes, you can load 20 Uber Gals onto this craft and have overwhelming battlefield dominance. But running 20 gals has the same built-in governance that Save Scumming does... it gets tedious really fast. Personally, I find controlling 8-10 units about right, and more than a dozen too much. Low initial Peasant abilities beg for more numbers to be effective, and in this the Harvester is on target. However, for me, pushing 20 troops around each turn requires a level of patience that I don't want.
I use my Harvester not to run 20 Ubers, but to get early 2x2 units to the battle. This is the true strength of the Harvester imo. Turian with early Hyenas and Harvester? Sure, super strong. Later, I run with 3-4 armored cars. This also trims the troop count down significantly.
