Sounds like ttk 2.0 is a return to slower ttk. See the announcement in the thread below because its not very clearly worded. My interpretation is:
-The current TTK is going to be the Alpha Hardcore ttk named 'Battlefield Core' and it will no longer be the default server rotation.
-The new ttk will become the default server rotation.
I don't like the sound of that. Sounds like they're banishing the current TTK -- which the community has clearly favoured -- to a hardcore mode. Hope this new ttk isn't BF1.
I thought they clearly admitted in a previous blog post that they realized the community overwhelmingly favoured the current TTK. Now it's being banished to hardcore and normal mode will be marshmallow shooters again ala BF1. Dice please.
