To me the point is not the (poorly chosen) time, but the question: What the hell did they fix or even work on?
If anyone would tell us whats going on then nobody would complain. It's again all about comunication...let us know what your doing.
"downtime - fixing problem x", "downtime - restart because some critical % of custumers reportet about y"
= Everyone is fine, because the reasons behind the decission are clear.
Now - you have angry players, left in the dark, and the best situation to start rumors...one may start thinking that FC only "hotfixes" things linked to...dirty stuff...starting with an e and ending with ***oits...
