First of all, I want to thank the BB for adding those improvements in the combat armories. And the last event (no, not that one), the egg rewards in expedition loot was phenomenal, just keep doing that in the following events.
On the other side, when BB added skills for generals, they somehow manage to disturb and slow down the movement of marshals, not to mention that marshals don't have their skill three. And loots and xp that you get when the expedition is successfully ended is mediocre, even tho you could lose up to 3k troops, that could be compared with militia or even soldiers, and the cost to built it isn't cheap or quick. And there wasn't any special marshal, except Black Marshal that you earn if you finish final PvP level. And expedition castle is decoration, like the bench. And colony could be lost in 12h. And why not saltpeter colony?
Oh, I think that the limit of troops in T2 colonies is more balanced than that in T3. The player could just flood the T3 with enough troop to brute force attack it to the end, so the defense has no chance, or give the defense chance by letting us decide where to put some of the defense towers.
So, give us marshals in the events, Black marshal means nothing when you reach final level, you know. Give us some kind of reward, just like you get some when you are playing adventures. Let the castle stands for something more then just a lotus in the pond. Please, don't stop to give us that hefty event loot that you did on the Easter.
All are welcome to add to this post something that they would like to see in PvP.
