I hear what you mean re: crappiest regen, but when you select the two final class stat upgrades, the hunter has more regen than speed or armor (I actually used to run my hunter Armor > Speed > Regen, but found that the Regen > Speed > Armor setup really lends itself to effective hit-and-run tactics, which suits me just perfectly). The speed helps you jump higher (def useful for getting the drop/angle on baddies), plus I feel like it makes a difference going toe-to-toe, since the strafing seems to help you dodge bullets like Neo from the Matrix.
