Some gw2 rant without hoping to make any difference.
Tldr: The point I wanted to make with this post is that being able to experiment with different builds should be a basic feature of a MMO. Because builds are useless with wrong stats, people can't experiment properly. Instead you have to follow meta builds to not waste money on equipment which is not ideal.
Once stats, runes and sigils are applied to equipment it is very hard / expensive to change without having legendary equipment. This leads to almost everybody playing the exact meta build in raids or fractals because the have been proven to work and discourage players to try out new things because it's so expensive.
Also every raider or fractal player is running around in openworld with their full berserker raid / fractal gear and getting 1 shotted all the time because it's to much of an effort to get a completely new set of gear for open world gameplay.
Now if you want try something off meta for raids/endgame fractals or a different build for open world you have get new gear, which requires time and money and depending on the stat of the gear (viper, minstrel, diviner, harrier) a lot of time. And after you get it, it could turn out it's totally kitten. What if trailblazer stats doesn't turn out as good in openworld as you have expected and you want to try out celestial? Well have fun grinding a new set of equipment. And the trailblazer's is new blocking space inside your inventory for years because you don't want to delete it.
This becomes even more extreme in T4/CM fractals. As you have the hfb, alacren backline for pug meta.
You want to try out a different rune for fractals?
Option 1: Get new ascended armor for 200+ gold just for that one tryout run.
Option 2: Override your current 6x5g Rune of Scholar each time you want to try new runes.
Option 3: Buy 6x upgrade extractor and then 6 again if you want to go back to your meta runes.
Other constelations like a chrono-druid backline and more more are perfectly viable but one of the main reasons it is not played is because you have to spend so much gold before being even able to play a different build.
You see where I'm going. Being able to customize your character and try out different combat styles is something you want to easily do in every MMO or RPG but it's somehow so hard in gw2. It's like the game telling you to play that meta and punishes you for wanting to try out new things. Only if you spent thousands of hours grinding your complete set of legendary equipment and having all legendary weapons you are allowed to experiment with stat combinations. I think the upcoming legendary armory just further escalates this problem.
In gw1 the strength of your skills are dependent on your attribute points which could be changed inside every city. Rune did not have such a big impact. Even so it was fairly easy to have different head pieces each with a different +3 rune.
In gw2 the strength of your skills are dependent on your equipment stats which is ok only if it woudn't be so hard to change them.
Since gw2 has already been out for so long I doubt any change is coming. I have also read somewhere that devs are aware they don't like the current infusion system but still no change after so many years. Still some suggestions from me:
Opt 1: Easiest but maybe not best - Make all ascended equipment always stat selectable just like legendaries.
Opt 2: Make ascended stat selectable but one have to unlock the stats. E.g. doing some achievements to onlock viper stats?
Opt 3: Same as Opt 2 but add Gem Store item to unlock all Stats?
Opt 4: End of Dragon buyers get stat selection?
