So far I managed to rejoin my old guide despite I usually play solo and rarely join their daily runs (team of 6, doily master quest + using mumble to comunicate)
Despite being passive, being able to share stuff via guild stash help my single player tremendously.
They put random rare that far superior than my current gear which drastically increase my survivability.
I still struggle to clear merc lab / malachai though, so Im kinda expecting to continue playing for next couple of weeks until uber lab.
Still havent research key unique / poe trade for my build yet, at least i got some progress.
