While I do not agree or disagree with the opinions of others who want change to come with healers, I stand by my opinion that this strike was not created in good faith. I believe it was created as a disgusted response to a video done by streamers that play on a level above the general player base.
Had this strike been created in good faith, it would of started long before this video existed or even better, further into this new expansion so people can give accurate feedback about the state of healers. As it stands people are bandwagoing the strike because of a video of something that has already been possible in game for a long time. If you have good enough players you can complete a dungeon without any specific role. This was possible for a very long time.
While the intentions of others getting behind the strike may be good, they should be aware of how it came to be and see that their message is supporting an "offended" response to a video more than it's helping healers in any way. One can also say if you are striking before you've even played healer this expansion, you have even less useful feedback to provide in order to enact change. You just can't form a valid opinion based on secondhand information. You are in fact hurting your own cause and looking foolish, and sincerely don't want that.
So I will not be supporting this strike. I'll play the game and form my own opinion based on first hand experience and I suggest everyone serious about change to do the same if they want to be taken seriously. If you already have valid feedback, putting it in the same cart as the strike is likely to hurt it and have it dismissed.
My concern is simply any positive and useful feedback being lost in a sea of complaints. If I'm wrong, well I'm just one voice and things will carry on as usual. I just don't believe this is the way to get the message across. A castle built on a crumbling foundation is likely to collapse under it's own weight.
