Otherwise maybe have haste2+ Honor march for 43.5% magic haste and use remaining song slots for 3 attack/acc songs instead of 2, if I read wiki correctly it's still 0.25% from magic haste cap but close enough. Honestly haste2 would be so much more useful if it's 30.25% haste, but I'm not sure if haste2 is exactly 30% or if the exact haste value is never properly tested.
