I don't understand why you are so concerned about it, or feel the need to point out how terrible it is.

It's a group of people that have known each other their whole lives, and this isn't like some FNM meta. Some of these players are brothers, or have been friends for 15-20 years, or married over a decade. There is a lot of history and a lot of need to make it as equally enjoyable for all parties as possible, not to mention we have a few people that can be a bit of a bother to deal with, but they can't be removed from the playgroup, most of us are related by blood, marriage, or decades of friendship and are more of an extended family that happens to play magic together than a playgroup that knows each other.

Some of these people only learned Magic within the last couple months or years, some of us have played since literally the first couple years of the game, some of them are children, some of them are nearly senior citizens. In our group I have been the dominant player and the guy building ¾ of the decks we use (though I of course build decks tailored to peoples requests).

During this time I have become infamous for consistently winning with Control decks, and to a lesser extent Combo decks, and the other big fish in our pond is a Combo first player. Guided by a literal diplomatic committee on the subject with all players attending it was decided with the input of everyone that the type of decks people didn't like to play with or against were "bullshit combo decks" and "wombat's control decks" with the latter as the most hated of all. I agreed not to make an oppressive deck like that (I also include things like Stax in this category) but pointed out that if I didn't have a strong controlling deck that combo decks would get out of hand, and people already not liking combo decks decided on a fair compromise.

Now you can say it doesn't sound like fun all you want, a dozen people enjoy the hell out of it, and this one minor compromise made it inclusive to EVERYONE regardless of age, skill, or playstyle preference. And more importantly, we all have decks that only use official banlists, that are completely broken and OP. Every serious player in the group owns 1 (or in some cases 2-3) completely cut-throat competitive decks that can be brought out when all the non-serious players aren't around without worrying about taking fun away from people that don't enjoy or understand that level of play.

There is no need to be so judgemental of other peoples playgroups and decisions, us doing what we do doesn't effect you in any way, and if you were to run into me at some mixed playgroup scenario you either wouldn't be playing against one of our restricted decks because we weren't in those houses, or you would be politely asked to use one of the 30 modern or 12 (and growing daily lol) EDH decks that had been balanced against each other if we were.

The very spirit of EDH is inclusiveness, and house rules are not only allowed but encouraged by the rulemakers of the format. I think that you might need to think about that next time you feel the need to criticize another playgroup's choices.
