There's some units I feel missed the mark, or rather we changed so little the impact was pointless and felt more like a "see we did something even if we really didn't" than an actual adjustment.
I think that's preferable to the severity of changes that the game saw under Relic. A lot of units went from hilariously overpowered to near useless (units like the comet, abilities like artillery cover). Changes aren't always intended to immediately fix a unit and make it viable; a lot of times changes are put in as low risk adjustments to make units more comfortable to use (changes like the most recent ones to the cromwell and to partisans). Beyond that, as you said, is just us missing the mark on some units.
