Almost every complaint about the ShB job changes could be solved with talents

And the reason being, the only thing important in the game is to make the health of the boss equal to 0...

I really don't see how they could change that without reworking basically everything, but for the sake illustrating what I meant:

Imagine adding a 2nd stat to attacks (like aetherial shield busting) and give a shield to the boss. Now, the new stat gives you no more DPS, but keeping the shield low helps the damage goes through. (e.g. full shield reduce incoming attack strength by 50%). Now you have 2 stats to take into account. In the same encounter, you can have monsters with very high HP and almost no shield (to which shield busting won't help you much), followed by monster with very strong shields (to which having overboosted DPS stats won't help much either)

And the only important thing in your set up is still "Make the health of the boss equal to 0".

Does it matter to keep the boss's shield low? Possibly, but if it's mathed out you can get around it by having this proper set up, that's the meta and you are bad for not following it. Or just make the healers peel shields off while the Tanks and DPS go full damage. Or just make the tanks do it. Regardless of what the actual answer is, it will be found, followed, and beat into the ground by the community. You'll still be expected to march in step with everyone else, making all those choices effectively worthless.

The community is DPS first because that's all that is important. A talent system won't change that. And changing the battle system might but we're still going to have community going Meta first and enforcing that on everyone. If the meta is DPS first we're back where we started. I mean I played Guild Wars 2 at launch and the only accepted way to play that game easily it seemed was just to dump all your talent points into Raw Damage. And while that wasn't the wrong way to play(the few dungeons I tried we lost due to not having enough damage so it was kinda mathed around having all that extra damage) it made it bloody boring to me seeing 4 trees to put points into and only one of them being Viable by both the game and community.

Look up Path of Exile too if you want a good example of "Unlimited Choices" but really only about 5 builds that work past a certain point.
