You know, it's permissible to group multiple sentences together into something called a "paragraph" rather than giving each it's own line.
I run with the sundial and Dying Curse.
This provides me with near constant trinket procs and enormous amounts of spellpower.
Although the hit and Crit of these trinkets is very nice and helps bulk out the stats, the real value of them to me is the procs.
I cant vouch for the proc rate on the egg as I have not myself tested it. If it procs as much from the fel armour ticks as the sundial does from spell casts then it might be an option, but i think this unlikeley.
However, I prefer the Spell power bonus over the Haste one as I believe it provides more DPS when you work it out.
In addition to this, as deep destro, random haste boosts throughout a boss fight might mess with your rotations pretty bad and you will probably find yourself missing conflags and CB's all over the place.
Wont make much of a difference to an Imp/FG Demo hybrid build though.
Top this off with the fact that the egg is likeley to be in line for the nerfbat in regards to Fel armour procs... Me? I'd stick with the Sundial.
