In theory, that's a hit rate of ~60% necessary to not waste procs. Yes, it's a small heal, but they add up.
Regarding HP generation through increased dodge/parry rates, with WoG on a 20s cooldown and with no timing necessary (due to the overheal absorb granted by GbtL) it should not be problematic to get 3hp within 20 seconds in order to keep WoG on cooldown.
Most tank deaths are caused by spike damage; something that a survival spec would help mitigate. Healer mana may also be benefited from this kind of spec, since a 102.4% capped SoI/WoGadin should be the most stable tank in the game in terms of incoming damage, allowing healers to use their more efficient abilties rather than spam fast and mana-intensive ones.
What I'm not sure about is how badly the surivival spec will affect DPS. A few K wouldn't be a big loss. Alys'razor isn't much of an issue, I'm usually taking out my hatchling with about 20 seconds to spare.
