I would like to add my support to this, or at least a more fun achievement system. Personally im a big big fan of achievement systems! But I really dont like to "kill the boss 25 times"..
I think the swtor devs have made a really great job with some quality of life stuff lately, like the core world changes (class story), crafting changes and such. I also really love the new story expansion, i think they're right on track! But i do really believe that the achievement system can be done a lot better and a lot more fun! A better UI and better achievements, cuz theres nothing more awesome than to show off what you have done! At least for me.
Basically I just want to say, i love all the quality of life changes theyre doing, and i would love to see it happen to the achievement system
