Of-course it isnt polished, its an unfinished game, its an open beta, its not meant to be good, its meant to be a teaser of how the game is doing and how its evolving
. Its meant to have bugs. This game has always had bugs and been iffy, i mean, look at the older builds for gods sake. The reason why the weekend 1 build was so good is because the devs had almost 3 years of preparation.
These developers aren't masters, far from it, their just a bunch of idoits having fun and making a video game for shits and giggles (and crack).
In short LET THEM COOK!!!
