Not bad, but Crit Shot and HTL don't work together (at least not in Mobile, but I've heard that it's the same on PC). It can help when HTL isn't active, but max'd HTL will be active pretty much all of the time. 10+ points is a bit much to put into a Skill that has such limited usefulness for a HTL Heavy.

Health Regen at such a low level is essentially a drop in the bucket if your Heavy is tanky with HP in the 15,000 range (i.e. Level 100 w/o any health boosts); it's even more ineffective by itself if you've got a good Bio weapon. Even a so-so Bio weapon outclasses HR for a Tank Heavy, since high Armor effectively multiplies your HP.

Also, no Fast Reload or Fast Movement. This could be a problem for players who want to incorporate full Hardplate for max tankiness, since reduction in Armor weight doesn't translate into a Speed boost and Heavyplate Gauntlets and Helms have Reload penalties.

More than 1 point into Concussion doesn't help much if you're using low RPS weapons (as this Build does, so I can understand why you put it in there), but the effect is multiplied dramatically if you have a high RPS weapon like a Proposition. 5 points should be the max unless the goal is to build a Concussive Heavy, but more than 1 point can be worth it if it's backing up the right weapons.

Finally, there should be at least 1 point in Brute Strength. No matter how tanky a Heavy is, getting stuck in a corner can be a losing proposition if the horde is big enough and the spawn rate is high enough. That extra 50% push strength is not only a big boost for just 1 point, but it makes the Heavy uncornerable and thus harder to kill.
