Tank Scaling still a massive issue

[StouterTaru]

If dps accs gain 14 str on a 20 ilvl jump, tank accs need to gain 14 too. By handing dps +14 and tanks +2 for this higher ilvl, eventually you will be back to square one.

Dps i320 to i340 upgrade is +208 main stat, roughly a 9.0% increase in damage (not factoring secondaries)
Tank i320 to i340 upgrade is +141 STR, roughly a 7.4% increase in damage (not factoring secondaries)

The gap is there, but it's not so massive that a major correction is going to be needed before the next expansion.
