Tank Balance

[Alahra]

I don't think it works to make "serious tanking" solely focusing on DPS, because it puts all tank in a bottleneck.
We should have more ways of improving so that each player can pick the tank that match their playstyle.

Well, in that regard, yes, it doesn't work for serious tanks that don't like to DPS, but SE is kind of stuck in the middle. If they make defensive tanking too active (following WoW's example), it will reduce the number of tanks in the long run for non-raid content (say what you will about queue times for DPS here, they have always been and still are much longer in WoW), as people won't want the "responsibility" on top of the more complex playstyle.

Things as they are now is a compromise, this much is true, but there is at least plenty of room for serious tanks to differentiate themselves from the more casual ones. It works even if it's not to your taste.
