You took some very questionable talents there.
- 3/3 Ravenous Dead is no way a tanking talent; 3% STR is not worth 3 talent points for tanks. The only build that are justified for taking that is unholy (for ghoul buff) and blood (just so they can go deeper and get necrosis+BCB, plus they have a lot of STR multiplier)
- 2/2 imp Blood Presence... A typical tank doing 3-4k DPS will heal 120-160 HPS. ONE Rejuvenation tick is 2.4k every 3 seconds - that means ONE Rejuvenation heals for 800 HPS. Seriously, 1 SINGLE Rejuv from a SINGLE druid heals for 5 times as much as your 2 talent points. That talent is useless.
- I have a mixed feeling about Mark of Blood. 4% of your HP is really not that significant, considering that you heal 15% of your max HP everytime you DS, and heal 20% of your max HP everytime you Rune Tap.
- Hysteria is nice to buff the DPS, but at this level I would be more concerned about holding threat, and your build is very lacking on that department.
TL;DR, I tweaked your build to fit the job.
