Weekend events

There are frequent weekend events where one type of troop or another changes sides. Personally I hate this. I understand the devs are trying to inject some variation and/or excitement into the game, but IMHO this is not the way to do it.

I would prefer something that helps everyone, such as:
-instant collections without buying feathers
-extra barbarian attacks

The reduced recruit, building or research times are great also.

Here's an idea: I notice that when a weekend event is announced, there is no way to comment or even give it a thumbs up or down.
If the like/dislike buttons were active on them, the Tentlan team could get an idea of which ones are popular and which ones aren't. At least they could if people bothered to do so.
