I personally went 20str/10vit. If you have the gear I see no point at all in stacking more vit and letting your Strength suffer. It may not get you pass the parry threshold but at least your damage will increase?(Could be wrong but I never looked into if Strength has a threshold that increases damage like parry has to increasing parry rating.)
I noticed just messing around with my attributes that when I went full vitality (I'm currently 4/5 Myth gear and +1 Relic) that the amount of HP I received per point seemed to get less the more I point after reaching 7.4k HP, managed to only get up to 7.6k after throwing all my points into Vit. With my 20str/10vit build at the moment I currently stand at 7.3k HP (very close to 7.4k HP though.)
I'll most likely stick with this after 2.1 as we'll have all those awesome buffs.. Don't see the need to be a Vit tank now, I saw vit tanks as a get as much HP as you can to survive and tank 8 mans tank since War just straight up take raw damage at the moment. :l
