Instead of hypotheticals, I would rather see proof of a 2H warrior tanking LBRS, Strath dead + live sides, or even full clear of BRD without taxing the healer and spending more down time drinking to recover, while using pre-raid gear.
Don’t get me wrong, I stated I am all for “fun” but when you are tanking higher lvl dungeons, it’s not practical, so either have a bear tank it and let the warrior 2H away all they want, or have them put on a shield if they are determined to tank.
Warriors lose their shield slam interrupts, among other defenses and armor mitigation when they don’t use a shield. I have been in a few groups where there was a warrior who attempted 2H, and I had to go bear form and pick up most of the lost agro, because they don’t have sunder to apply, etc.
To each their own, I just don’t see any good guilds/groups ever subscribing to any form of 2H tanking.
