You can go full STR with a static i think for warrior,don't think it's great for a paladin.
Actually before the 2.1 i would have say full VIT but now if you know when to use inner beast and the others CD you can tank really well with a full STR build.I already tanked the extreme primal with my warrior(7k9 hp with food) and did the 4 turn of bahamut.Not playing MT on the T5 tho our paladin is here for that.
There is stricly no problem in tanking with full STR as a warrior.
