... adding Surge will give a -small- benefit, adding Alac will give -zero- benefit in practical application.
Thats your opinion, not fact.
There are lots of situations where EMP/(SP?) just will not save someone, especially if it does not crit. But Kolto INJ/INF will.
In my opinion, that 0.2 of a second alacrity takes off both of your biggest heals is a life saver in pvp. Both of your own, and others.
