It seems to me that SE had realized that tank/dps balance is off from what they want. They made major adjustments with the release of SB. Now they're trying to get the player base used to their (SE's) idea of balance. At the same time, they aren't able to fully realize the results without letting the players play. I think they either did a decent job taking player feedback (i.e. stance swapping) or their numbers corroborated what player feedback was saying (i.e STR acc). I think once the balance is to their liking, tank and DPS STR will rise at the same level and tank enmity will be a constant. Personally, I think it does no good for a tank to compare their DPS to a damage dealer. I think a tank should be able to hold enmity while pushing out their max DPS, but a damage dealer should always do more DPS.
