Wicket/Talzin farming...I don't understand the complaints.

I think the biggest problem is how quickly they churn out characters. They release Talzin after just releasing BB8, Han and Chewie. Then they're gonna release Jedi Rey in a couple months to coincide with The Last Jedi. You can't even focus on getting and gearing a character before the next one is out. This leads to a lot of panic farming which I hate. You pretty much have to do that stuff to stay competitive in Arena (when they release really good characters like Thrawn for example).
