as a pld i always have and always will stack vit. the more hp you have as a pld the better your personal stoneskin/divine veil/spirits within works so thats what i feel i need and has worked wonders for everything before 3.0 and still currently works fine. granted i used 110 pentamelded for last leg of 2.xx with fending str melded but str no longer affects block/parry % so im 100% vit now
