Instead of a talent tree, I'd rather see SE demand more "talent" by the player. Go back to having tank stances with damage down and Cleric Stance with damage up/heal down.

Take tank stance for a second. Enmity is a resource. A tank keeps hate whether they are 1 "unit" of enmity above #2 on the hate list or 1 million "units" above. This resource should have value. We should be able to turn off our ability to accrue hate at an absurd rate (and it IS absurd) and increase our damage instead.

When it comes to enmity, it is possible to do tank swaps while one of the tanks has NO idea what they are doing. Let's say MT is clueless - MT takes the tankbuster with debuff... OT provokes. Takes the hit. OT Shirks. Hate is back on MT. MT does nothing.

Let's say OT is clueless. MT takes the tankbuster and the debuff. MT Shirks. OT takes the hit. MT Provokes. Hate is back on MT. OT had to do nothing.

And while they are at it, they shouldn't have changed accessories. HP is another resource. You are alive whether you have 1 HP or 200,000 HP. If you don't need 200,000, exchange some of that HP for more STR (and more damage). Change the damage formula again and let tanks use STR accessories and meld STR.

None of this will ever happen of course. The game is simplified in almost every way imaginable. But, a return to ARR tank stance and healer stance would demand higher skill by the playerbase.
