There are very clearly two different player bases for this game, those who want a challenge, and those who do not. I feel for Anet having to try and decide which of these two groups gets the attention in a given content release.
Some people will probably disagree with me, but I don't think you should be allowed to participate in the strike missions that require lots of cc until after you've unlocked the Icebrood mastery for them. People complain about LFM having requirements like raid KP, but then don't even put the effort into having the mastery done to be able to help the group succeed, which is even easier than getting proper gear. At least if everyone had the mastery, you can increase the chance of not failing the cc bars that lead to wipes on BS and WoJ. Strikes have other problems too, but this one is something that should have been implemented from the beginning. You need the mastery to get the rewards, so why not make it a proper gate for entry instead of this half in half out thing?
