If you're interested in inference, then your primary concern should be power. An imbalance in regressors isn't a big deal so long as you have enough observations to give you your desired level of power. 1 tall person in 10 observations is a bad thing. 100 tall people in 1000 observations is better. – Demetri Pananos.
