Possible adjustment to tank stance

Since I've started here, losing tank stance every time you get synched down has been a massive QoL failing of the game. I understand that stance counts as a buff, and all buffs are removed upon syncing down to avoid being able to bring in higher power than intended, and that is why I think tank stance needs to no longer be a buff. Instead, tanking stance should be done away with entirely, and simply added as a passive that is gained at level 10, that increases enmity generation as far as the current tank stances already do. To counter this, tanks should also gain an enmity reducing stance, which they can turn on at any point to cancel out that enmity generation buff. This would mean that the only time you have to bother with stance is when you do NOT want to tank, rather than every time you do. All tanks in duties, by default, would be generating appropriate enmity up until they disable this by putting on their reduction stance/buff.
