I'm not a maths guy but our harderst hit spell is an auto crit in the initial burst, so maybe and only maybe, it's better to have haste instead of those extra % crit.
Hope the math guys step forward so we know if haste is more dps than crit.

From Elitistjerks:

"In ZAP, assuming EM and BL stack, using them together is roughly equal to using them apart until about 900 haste rating (+ buffs, ~38%). At that point using them separately is better and it's still a DPS increase over the old EM. By 1100 haste without 2t10, if you use new EM+BL together it's less DPS than using old EM, but new EM decoupled from BL is still very slightly higher DPS overall (~10). With 2t10 new EM is clearly better than old EM whether it's used with BL or not.

This is assuming a 6.7% uptime on BL (that is, 40 seconds every 10 minutes) and an 8.3% uptime on EM (that is, 15 seconds every 3 minutes) without 2t10 (which increases EM's uptime to between 15 and 19% depending on haste).

So:
Haste < 900 = no significant difference between using EM with or without BL
Haste > 900 = better to use without BL
That means it'd be better to use the new 3.3 PTR incarnation of EM on cooldown every cooldown than to wait and synch it with BL.

If most of us save EM for use with other cooldowns at present, this change would increase our EM usage and uptime as well as increasing the DPS of the effect, which adds up to more of a DPS boost than the spreadsheet will claim (as it assumes EM usage on cooldown every cooldown anyway)."
