I strongly disagree with this. To me the Antagonist system is a core part of the game and is what makes it really fun. It shakes things up and makes the missions more interesting rather than doing the exact same thing over and over. I also love there being a lore reason for it. Even as a Raider I get excited when an Antagonist joins as it just makes it more fun. It's not just me that feels this way. Loads of players love the Antagonist system and honestly I'd be devastated if they removed it. It's also worth noting that the Raiders have the advantage over the Antagonist, not the other way around. I find myself getting more frustrated playing an Antagonist rather than a Raider. But that's how it should be. It's hard! You have to think and play a different way as you just can't take on four players at once. You have to be clever.
I'm on the same page as you are. I like the Antogomist system and I can live with the Mentor matches. If you give the people the option to toggle mentor and the Antagonist system 85% of the time they will not participate in it.
This is MS's vision. They wanted to create a game that was in my opinion is spontaneous. Going into a match you don't know if it will be a mentor match or if you will fight an antagonist. You might get both. Who knows. That's what makes it exciting. This is what makes it stand apart from other games. The Antogonist system adds a little something to the daily grind for gold and blueprints. It changes the flavor. I don't like the grind. Playing the same mission over and over and over with nothing different becomes boring. Antagonist adds a little fun to it. Not to toot my own horn but I body antags.
The Antags aren't the problem in my opinion it's the rookie players, the baby Harecs, and the mentor system. The biggest problem being we can't communicate with other players properly. All we have is that prompt wheel. The 2 prompts on that wheel most used are "ok" and "come with me". We need one to be able to let them know when they need to do something and if they're doing something wrong. Like killing elites when we need the aleph. Or dropping off their Aleph.
Antags on mentor matches maybe shouldn't be a thing. I've actually seen more high level players quit Antag matches becasue they got matched up with low levels. With that being said I think a good solution would be if you aren't a high enough level to be an antag you shouldn't meet one.
