I too, made use of +VIT accessories which I obtained from numerous runs of Lakshmi EX.
The numbers may be small, but you can always fix it with Strength Materia!

And, even with 0 STR accessories before the patch, I never had any problems with tanking. DPS is not a main issue for tanks. It's secondary or even tertiary (with Tenacity on top). Just be grateful SE's taken this measure, alright? They don't want to make tanks have higher than expected DPS.
