If you don't speak up for what you dislike, it won't be changed. The forums are currently full of the same threads on like three topics.
The devs are much more likely to recognize these are issues than if there was only a single thread with no other complaints.
It's obvious that many players are upset and if SE wants to be a good company, they'll recognize this and fix future content to make the players happy.
It's wrong of them to have made the armoury system one of their main selling points at release, and then make it impossible to play all those characters at end game; and then for mid tier, too.

I don't know why people keep encouraging mass amounts of players to quit funding a game they also play any time they raise their concerns. You do realize that if everybody left over being upset over one thing, they'd probably just turn off servers since no one was playing, right?
