In my previous post I sang the virtues of going sword spec in the arms tree, rattling off the (often overlooked) benefits of the spec.
One of our visitors argued I had missed the most important drawback of sword spec - and he was right. No minor drawback either, it reduces the effectiveness of the proc by something like 25-33%.
The theory was that when your sword spec procs it resets your swing timer. This is no problem for procs off of white hits, since the timer would be at 0 anyways. But for yellow hits, having a sword proc when you were 0.1 seconds away from your next white swing anyways means you get next to nothing. A 0.1s faster swing. You are not actually getting “an extra attack” as the tooltip suggests. Rather you are getting “your next attack immediately”. So its still good if it procs early in your swing timer, but the farther into your timer you get the more the proc becomes a very minimal haste type buff (for 1 swing) than it does an “extra” attack.
Frankly this is mind boggling. The tooltip is misleading, and with this knowledge the spec is strictly inferior to axe or mace. It is like spending 5 points in axe spec for 3% crit, since a good chunk of the procs will be basically wasted. Any proc off a yellow will be a haste-proc, not actually an extra attack. Sadly one of the biggest advantages I was arguing for in sword spec was that it gave a nice damage buff on hamstring and pummel procs, and gave rage on all yellow procs. Now we see a lot of those “procs” are damage you were about to get anyways, rather than free damage.
The evidence below:

The screenshot shows this:
45:16 - victory rush (proccing ss)
45:17 - SS proc.
45:21 - white hit (+4 seconds since SS proc)
45:24 - white hit
45:26 - hamstring proccing SS
45:26 - SS proc
45:30 - white hit (+4 seconds since SS proc, +6 seconds since last white hit)
The first proc came 4 seconds after the last white hit (you cant see the previous hit unfortunately). Sword is 3.6 speed so this is what we would expect if the swing timer was reset after the proc.
The undeniable proof is in the second proc. If the timer was not reset my next white hit should have come either at 45:27 or 45:28 (3.6 secs after the previous white hit). However it came at 45:30 - SIX seconds after my previous white hit, 4 seconds after my Sword spec proc.
What blizzard was thinking in doing this boggles the mind. But do I care enough to go back and craft the ugly looking axe?
