So you don't like this wave? That sucks for you, because I think you're going to be missing out on some fun. Hopefully the next one will make you happier.
Agree...
There's nothing wrong with disliking a given wave or ship. I don't care for the Houndstooth myself, even though it looks pretty cool. I didn't care for the IG-2000 either, and you know what I did?
I didn't buy one. There's nothing wrong with stating your opinion, but when all you do is fill thread after thread with negative posts, no one is going to want to listen to you. Do it often enough and you'll start to get called out on it.
There's simply no reason to do that either, it's not like anything is going to change about Wave 7 at this point. They're not going to swap the Tie Punisher out for the Scimitar, they're not going to swap out the K-Wing for something else.
So negative comments about wave 7, will after a point accomplish nothing but make people who do like it upset with you, because no one likes hearing things they like trashed. It's a pretty simple concept and one everyone who can afford to play this game should be mature enough to understand by now.
So if you don't like something fell free to comment on it, but after you've made your opinion known you should follow the very sage advice of "if you have nothing good to say, then say nothing at all." Because again, no amount of posting about how much you dislike wave 7 will have any impact on anything, other then making people upset with you.
