I assume in some maint of March (or automatic) the server who are 60 days old by 1st March will get this enabled, same for each subsequent month.

The wait time is therefore somewhere between 60 and 90 days since start of server. 60 days for the server that is lucky enough to reach the mark on the 1st of month exactly, 90 days for those that are exactly 59 days on the 1st of a month that have 31 days, thus waiting for 31 more days for a total of 90.

Ah, but many other server went without reward for up to 6 months, getting them for the FIRST time on their 7th month. If there is an actual "rule" so that new server miss out on 2 month each, it's hardly unfair.

Personally I don't quite see why the rule is there, since arena is Xserver, so it's not like someone can abuse the system by farming it early in their own server or something but... I like having rules and following them. If only EVERYTHING they do follow some strict guide line (I'm looking at you, server merge people) the game would be a better place.
