I think the main point for me is that one person's enjoyment or even a minority groups enjoyment is not a good indicator of the overall state of the game. Competitive players are very loud on these forums. Competitive players who are not happy with certain things are even louder. That doesn't mean they are the majority. It also doesn't prove the opposite, so I will refrain from saying the game needs to remain as it is.
I think many of the complaints are expected and necessary. Power creep and complexity are bound to continue. Otherwise people would get bored with the same old game and move on. Again speculation, but from experience, the new shiny makes sales. You're not going to have a good business plan by having the original core set being the top of the meta for the game's entire existance.
I don't mind suggestions for tournament changes. The one suggestion I've seen that I really like is a tournament series legal card list. The casuals aren't even touched with this, and the tournament players get a finer granularity of balance. Some mention a reboot of X-Wing back to a new core set. I don't see that happening anytime soon.
