Ubisoft, when are you gonna realize that online only is TERRIBLE!!! You shut down the servers twice in 3 days!!! Stop with this online only crap!!!! Thanks for ruining my nights by shutting down the servers!!!
There are definitely pros and cons to games being online only. One benefit is the uniform maintenance for all players simultaneously so no one is playing an outdated edition. As for servers shutting down, we announce maintenance times on our Twitter days beforehand and post again when they're about to happen. For non-maintenance server shutdowns, I advise you reach out to Ubisoft Support to see if it a solvable issue.
Besides that, please be sure to include details of where/when/how often/during what activity/etc. you are getting these shutdowns. Thank you.
