How to do the Rotation

Dasher isn't necessary and TA still does more damage sub 50% than EA. Also, if the initial hit of EA is deflected, you do not get the T4 Mortar buff but on the flipside, I have never seen TA's last hit ever deflected, only the ticks leading up to it. TA also procs two damage sources above 50% which gives two UV procs compared to EA's one.

The rotation is easy, you just basically put TA in for Bio in the normal rotation. The only difference is, you need to monitor TA stacks and dodge roll out of TA at 8 stacks on the target. When you see the 8 appear and you dodge roll it will go up to 9 giving you the max damage and you follow the dodge roll with BC. Then by the time the GCD of BC is over, your TA will have done its damage so you can use your MS buff then back to BC until TA is ready again.
