Help in trinket decision?

[Jademist]

I recently just acquired Darkmoon Card: Illusion and I was hoping to trade it off with Sundial of the Exiled since apparently SP > Haste > Crit. I have Abyssal Rune as my other trink. Should I switch Sundial or not?

procs are also great you know. get rid of your darkmoon card. it sucks

The darkmoon card isn't horrible for arcane neither is the rune.
Since crit is the 3rd stat you'd want for arcane the passive bonus on the sundial isn't that amazing
The proc however is semi decent if you keep an eye on when it procs and line it up with IV.

So if you're badges would otherwise be rotting away get the trinket, if there's anything else you could buy that's an upgrade get that first.
I'm not sure what you're raiding atm but you might want to consider getting some more hit and speccing into fire in which case sundial would benefit you more.
