Average player here and loving these new settings especially no automatics. I played about 20 games yesterday, and getting ready to play some more. I am doing what I can to contribute to the data. One thing I noticed was an above average amount of lag. Not me but other players. There was close to every game with one person lagging a lot, at least one quitter as well.
I don't really think we need to add different weapon variants like the Tactical Magnum, but merely place a few magnums on the map for ammo. I haven't had too much problem with running out. I make sure to pick up from dead Spartans. Plus I don't survive very long anyway.
I understand that you will be looking into changing the AR in the hopes of returning it to the HCS playlist. I hope this does not happen. I am thoroughly enjoying not having any autos to deal with whatsoever, and I believe the AR is fine the way it is. It just isn't a good choice for competitive play.
Finally, I believe keeping the TA playlist unchanged, and having a dedicated HCS playlist is the way to go. It seems inevitable that you will be removing radar altogether, and there are those of us solo players who can't/don't use a mic, but also enjoy a variety of 4v4 slayer and objective games, who will miss having the old TA to play on.
Thank you for making these changes. I may not be a pro, but these are highly appreciated.
