depends, if u use a weapon w/ high rate of fire, concussion is useful, if not, don't use it.

~50-60 health regen is good for a heavy, so yes, go with the 4 health regen and the tissue repair on your armor.

1 crit shot is always useful.

If you are going to use an HIKS 3100 for bossing, don't use concussion, that thing doesn't have a very good rate of fire, and put 2 or 3 points in field supplies.
