Is the game stable atm or should I wait?

[Highspeedpixels]

Played the game offline before, up till the "raid" bosses where I felt it gets too tedious solo.

I was looking forward to play it, but the track record for the game seems to be buggy-ish whenever new patch/big update launched.

So yeah, is it working fine now, is there any big bugs or issues (I see private server/antivirus issue, does that include offline as well?) or should I wait?
Also, how bad is brutal mode? Can we just toggle the new bosses move (so I heard) since that seems to be the highlight - for normal mode or something?

Many thanks
