Nice analysis but I got a different opinion on this. Im talking about CONSISTENCY. If you got 52 dmg reduction like me on my tank and u get a 20K hit, you will only receive roughly 10K damage, EVERYTIME. Shield is only a chance. Even if you got 50 percent shields, you might as well get the whole 20K if RNG hates you. Furthermore you dont have 100 absorb, so even if youre lucky only half the dmg is absorbed. But high HP also increases survivability, so the healers can leave you longer unattended without you going down. Also depends a lot on class I think. Im jugg tank, so I dont get shield bonus or anything, can never reach those insane shield stats of assassins or PTs, so I basically rely on my high dmg reduction, HP and my defensive CDs.
