Try lurking arm build (growing infestation/within my reach/lingering spines). I feel like Universal carrier on 16 is still the best choice for the reason you mentioned and also even though not a lot but it still provides constant healing almost like healing totem. After taking growing infestation once I can't go back, without this talent the lurking arm seems much weaker. The Vigorous reputable is very tempting but I feel like it's often hard to complete. If you're planning on taking Universal Carrier on lv16 then it's better to go "one good spread" on lv4. Lv13 roots talent is good, but it's hard to preform IRL. Lv10 and 20 on your choice, I prefer shove. Stukov is pretty squishy, It's tempting to go ham with his crazy AA dmg, but as with Rehgar, you better stay behind in team fights. I'm not sure what to add, I feel like I will say obvious things, so... :) He's less like a single target save, since his heroics are not heal related. More like a utility support with aoe heal. The lurking arm is really cool.
