Mesmer staff trait only semi-working
It doesn’t affect Illusion-Summoning Skills because although they are staff skills, they are only skills that are given by staves because they are categorized as Illusion-Summoning Skills.
To reduce cooldown on those, go down the Shatter trait tree 5 points in. Because of that trait, they don’t get reduced by other weapons or it would stack and be ridiculously short (e.g. 11 second warlock).
Also, your Auto-Attack has no cooldown, just a cast time. 0 – 20% = 0.
As for Staff 2 not getting affected, I’m not sure about that.
As I said, I already have the 20% cooldown reduction on those.
And including the major trait for the 20% cd reduction on staff skills, I should get 40% reduction on my skill 2 and 3. Therefore, a 6 second phase retreat, and an 11 second warlock.
If they don’t reduce all skills, than they shouldn’t have written 20% cooldown reduction on staff skills…
I also found someone else writing about the combination of the traits, a couple months ago, saying that he indeed got a 6 second phase retreat. That’s where I got the idea for this build. It seems like they ‘nerfed’ it, and thus made the major trait rather useless…
