I do a lot better in BF4. I do love the MAA with zunis and setting up in the middle of the map. It's always fun to watch the entire other team come after you almost at once. If you think a MAA just out side of the main base is bad, one in the middle with zunis and proxy is far worse.
How can you say it worked far better? It's based on the same engine as BF4 thus it has the same short comings when it comes to hit reg. You have cherry picked memories.
This video looks like it was something straight out of the first 4 months of BF4:
I use IE just because I don't have to worry about it crashing and kicking me out of game like FF does. The only settings I have changed are in the Privacy tab. I allow first party cookies, block 3th, and allow sessions. All others are left alone.
Only time I really noticed problems with IE crashing was after I installed Ad Block for IE. Even uninstalling it did not fix all of them, but it did fix most of them.
