I agree. 8 players vs. 8 players is perfect. It's perfect on Blood Gracht, The Radec Academy, and it's really good for the market as well.
I just felt like 32 players was a little too much. I'd often leave them if they got too crowded. I just felt with all the corners, alleyways, high ground, low ground, and pathways, it became too hard to play on. There would always be someone everywhere you look. Sometimes you need a few seconds to get to somewhere you would like to go or be. But instead you are too busy running into an enemy every 3 seconds which doesn't allow for you to do much. Whereas in an 8 on 8 I'd have space to do team objectives without getting shot at 24/7 by enemies. And I'd be able to find a spot I like and traverse the map without being raped. And face it, it would happen to even the best players too.
No matter how good you are, when all the people are near eachother on a 32 player map, you aren't going to be seeing big kill streaks... You are just never safe.
