How should tbn get changed/updated?

[Carighan]

By that logic it'd be strictly preferable if every tank had every effect separated and as many of them as possible, no? Maximum flexibility! And it clearly has no downside, just allows you to spot more people!

The button-bloat comes from being already able to do that. TBN can already be used on other people. We already have a percentage damage reduction for partymembers (even multiple!), independent of three extra percentage damage reductions on ourselves. This means that if the need for more of this exists, it should come from CD-reductions or CD-resetting trigger effects on these abilities instead of adding yet another button for yet another CD to track. Plus it's not neutral, it comes with the very real downside of this approach of "just add more flexibility" washing out the identity of every individual effect. Which can be good in a pure approach (a shield is a shield because it's a shield, oh ja), but in FFXIV we are rarely doing that. Meaning that just like GW2, skills derive character from their plethora of extra effects. and then instead you get Oblation which is a 10%DR with no other effects on a fairly long CD. No trigger effects, no extra shielding, no runspeed effects, no healing received, no nothing.
