Just for fun, WAR can chain defensive abilities indefinitely:

IB (6s) > Infuriate > IB (6s) > Foresight (20s) > IB (6) > RI (20s) > IB (6s) > Vengeance (15s) > IB (6s) > Infuriate > IB (6s) > ToB + Conv (20s) > IB (6s) > Foresight (20s) >> etc.

I just thought it's fun if you wanna turtle as a WAR for whatever reason lol.
