Maybe it was already known but I just found out that Deadly Haste affects Awe.
Although Deadly Haste is meant to only affect spells, I am trying different combinations with it (2.5 second recharge, half second cast siphon speed and a 5s recharge Disrupting Dagger were the best I could come up with). Whilst looking through the list of half-range spells I noticed Awe which is a skill and decided to test anyway since Deadly Haste had a major bug before and looks like Anet just threw it together without ever testing.
With a silencing Dagger Tang, Deadly Haste, Awe, Horns and Moebius you can some funny stuff. ^^
A bit expensive at 10E but well worth it.
The cast time is also cut from 0.75s. So with the usual 13CS, you get a non-elite Daze that lasts 6s (7? not sure) on a 10s recharge with a 0.33s cast time.
I'm off to harass monks. Abuse it while it lasts I guess.
