Very sorry if this has been dealt with already.
Will the 375 tailoring specialisation matter in WotLK? Example: my priest is a 375 primal mooncloth tailor, and I don't know whether that specialisation will continue in the expansion (i.e. pattern sets specific to primal mooncloth tailoring).
I ask because I have respecced my priest from holy to shadow for levelling, and I want to change specialisations from primal mooncloth to frozen shadowweave for maximum damage. I don't want to do this, however, if at level 80 I must change specialisations back to primal mooncloth (or an extension of it) to benefit from new patterns for holy priests.
