Here's the gen: http://www.settlersonlinewiki.eu/easter-event-2015/
And I am not even slightly excited by the prospect, I have to say.
For those of us like me who have none of the old eggs, there's very little worth going for. The Legendary Veteran is rubbish- troops "increased to 200"! I don't have a single general with less than that. The MMA and real Veteran are only available for old eggs. Same with the fast explorer.
I mean, if you don't want to make the event fun, why bother having it at all?
