How does everyone feel about skill speed?

[kysulli]

That's a fallacy. Monks aside, having 100 SS (going from 2.5s to 2.4s GCDs) will enable you to finish the last attack that you would have otherwise been unable to execute, [4.2% * # of prior attacks] of the time.

E.g. if you have 10 attacks before the boss mechanics on your head, then there's a 42% chance that you gain an extra attack while leaving the boss due to skill speed.

It's funny to see people demand a 100% chance of a full new GCD from skill speed before it's worth anything, when they value crit so much even though it only gives a 7% chance for half of an attack.

You are making skill speed simpler than it is.

Every attack you make at a GCD lower than 2.5 is time banked equal to the difference between the two GCDs. For every 24 hits a 2.5 GCD makes, a 2.4 GCD will make 25. It will take 60 seconds of uninterrupted fighting to guarantee that extra hit; assuming you are executing abilities on time, not using off GCD abilities, and not pausing for positional changes. Every millisecond you waste not fighting after the GCD resets will mean an equal amount of banked time lost, which will have to be built back up again before you benefit from a guaranteed extra hit.

Like you said, banked time for an extra attack can be cashed in if you disengage before your higher GCD self has caught up. However, this is entirely based human error and boss mechanics. Assuming no human error and constant boss mechanics, the extra attack will either be hit or missed when disengaging, with no in between. SS would have to be adjusted on a boss by boss basis to benefit from it. If not and you end up missing your extra hit every time you disengage, then you end up with a situation where banked time depletes every time you disengage longer than GCD reset, and that guaranteed extra hit could end up happening as late as 2 minutes instead of 1 minute.

Is a guaranteed extra hit every 2 minutes with 100 more SS worth it? I think the 2 minutes is an exaggeration, but it is possible if you lose all your banked time every time you disengage. Again, entirely based on boss mechanics and human error.
