I like this sugestions =)
What I would really like is a rework so tanks need to dps less and tank more. But this will never happen and we always going "DPS" path.
Right now tank stance is so "useless"
If they want us to focus so much in DPS, they could just make dps stance passive, and make tank stance a 30s buff without or with less dps penalty, with 90/120s CD. LOL
