I came up with an opener which works for me well, you can tell me what you think about it:
HT - Battle Litany, BotD - ID - Dragon Sight, B4B - Dis - geirskogul, jump - CT - Mirage Dive - 4th - Spineshatter - 4th - Mirage Dive - TT - Dragonfire Dive - VP - Life Surge - FT - 4th - 4th - repeat
this one aligns the cooldowns for jump, geirskogul and b4b quite well later on and my rotation feels more fluid.
