There could at the very least be some entry level schematics at 50. as it now (for synth at least if memory serves), you get some level 49 patterns and a a small sample of 50 ones (belt, bracer i think) that require mats from HMs.
Admittedly, the level 49 stuff can be reverse engineered into purples with (i think) armor level 123 stuff.. but..
Oh well
Ill be raiding once the guild has caught up anyway
