Thank you.
2. As my friends who used to play on Ubi told me, it's not really possible to have a proper match there, because players mostly try to play games quickly, without proper development, and in 90% of long games, there are always some misunderstandings, or someone leaves, or the game crashes, or it lags! If you play there, you know what I'm talking about!
Secondly, your categorical statement suggests that you haven't played against a decent Necromancer, but against some noob... Especially if he was beating you with two castles while you only had one native castle.
