Watering tanking down into standing there and taunting is going to bore all of the tanks who have become accustomed to the changes soe has made to tanking over the years. You, the Dev team, has been pushing the game in this direction for four years and now this late in the game's life you once again want to completely reinvent the game for no real reason.
It seems like sony purposely does these complete overhauls for the sole reason of reminding the customer whose vision this game is. It's almost like they think "Well we want to try this now and if you don't like it then too bad." All they usually end up doing is [Removed for Content] a lot of people off as they show they are not in touch with their customer base at all. In return they lose more subs and waste money that could have been better spent adding more content or fixing real issues.
Who is going to [Removed for Content] you off more, someone who is standing there yelling at you or someone who punches you in the eye? Sure taunts distract you for a moment, but when that Brigand sneaks behind you and stabs you in the spleen there is no amount of taunting that is going to distract you from the wound he just inflicted. The only reason why taunts are in mmo's of this nature is due to the fact that they are so deeply ingrained in the lore of the genre. Sony, be different, leave dps tanking as an option and just fix defensive tanking since there are plenty of times you do need to be in defensive.
Offensive tanking on live isn't too far off of what it should be. Some minor tweaks to the actual dps that tanks are doing was all that was needed to balance that aspect. Tanks should be able to put up T2 dps type numbers and if they are indeed doing more than T1 dps classes (the group that supposedly has complained that tanks do too much damage) then either the dps'ers suck, the buffs in the group benefit the tank significantly more than they benefit the dps'ers, the tank has an obscene amount of dps buffs on him or a combination of all three. Usually it is more of the former and the dps'ers just suck.
As a Monk tanking in offensive stance I already run a much larger risk of taking damage since our mitigation boost as well as our uncontested avoidance is directly tied into the defensive stance. If they had just tweaked offensive tanking there wouldn't even be a need for the 5% increase to damage taken on offensive stance. All they would have had to do was make it so every tank's stances worked like a Brawler - everyone loses their mitigation bonuses and uncontested avoidance while in offensive stance and tie those very things in with defensive stance only. Problem solved without completely revamping combat/aggro mechanics.
The only thing they would have had to overhaul was defensive tanking. They could implement the current changes on test and apply only the defensive tanking mechanics.
Instead of taking this approach and slightly tweaking offensive tanking and fixing defensive tanking they are once again reinventing the wheel when it is completely unnecessary. Why focus the little bit of money from dwindling subs into redoing combat mechanics every 1 - 1.5 years instead of tweaking/modifying existing mechanics and offering more content?
Personally I would have much rather seen them do what I've mentioned. It would give people more choices in how they want to go about things. Instead it is literally watered down into two choices....click this button for tanking and click this button for dps'ing. There really isn't much middle ground now and there certainly isn't a lot of choice.
