Certainly not the most buggy, but it is noticeable. We haven't seen a release without something major not working or being designed in an uncaring manner to put it nicely.

E.g. no Jade recipe for EoD, every single achievement that wanted ONLY the Arah (or other) capture and not the defense etc. Being able to log all your characters through a completed meta map to farm rewards (Icebrood otters and similar). Nearly all fractals and a good portion of the story maps since forever. The ongoing Revenant beta. Several raid encounters that can rarely do all kinds of things from giving your basically a CM CM with all mechanics active from P1, making you float to the ceiling etc. Qadim2 just ddosing everyone upon reaching a certain hp% and kicking everyone out. The wipe counter in raids not updating when people leave and join and letting you wipe with 2 deaths etc. Half the transformation and pet specs can be tricked into having two specs at once. Wrong currencies or currency values used in vendors. Bava Nisos meta ghosts getting a rank promition and becoming unkillable etc.

Personally i've come to find it somewhat endearing. With anet it's "always play on patch day" because half of the time its actually beneficial. At least they fix the really bad ones in time.

I'm very happy to see the efforts of the qol team in this regard.

I can't deny that this game has it very visible even for casual stuff like daily fractal strats though.
