"Kill Trading = Ban" announcement made AV worse
Yes, it made it even worse. Not only are we back to the meta where 15-20 people on every team are afk or only casting a single ranged attack every couple minutes before hiding in stealth. Now, we got more players afraid to take risks, afraid to die, because they're afraid if they die too often/quickly, they'll be banned for trading (regardless if that's what they were doing).
Honestly, the game was more fun when people were willing to fight and die. It's a BG, rezes are free and give full regen. Let's play "King of the Bridge" and fight for control of the center (between the two pillars). If you die, rez and rush in for more hectic melee action. Kill as much as you can, try to keep the center, but don't worry if you die...you'll just rez with full health and mana to rush in and fight some more. And it'll be more fun then waiting for pushes on "your side" of the bridge or running to die without fighting.
