You are not seeing the forest from the tree. Or you don't want to, I have no idea.
I will try to break it down to you one last time: The way they handled the "gift" and the time period they stamped on it is bad.
It's quite simple honestly, in WoT most of the gift tanks they handed out was on log in. (simply put you loged in the game and you received the gift). Also the time period they put on these events wasn't only ONE DAY.
We are talking about the same company (WG). If you did something good (even if it's another game) try to improve it, not degrade it and leave people with bad taste in their mouth.
