1.) The Team Optimizer will use the gearing strategy you have chosen in your public profile, otherwise just fall back to our default. For 7.2.5 it will use our “auto” strategy which will be a collection of many strategies. You would have to set up the type of fight you want to base your loot on.
2.) The default strategies are based on live. There is a 7.2.5 build of the simulator available, and we’re in the process of making new gearing strategies.
3.) The default gearing strategy isn’t based on using Blackout Combo, which is the talent that really favors haste on live. Haste is one of those stats that “feels” good to a lot of people because they like to be GCD locked and execute a “rotation” while tanking, but, our simulations show that you won’t really keep yourself alive longer by doing so.
4.) I made an update to the rotation for 7.2.5, but it’s not compatible with the live version… set the “version” to 7.2.5.x and your simulation will run. Sorry about that.
