Actually, no offense, but Metal Robot got many High ranked crafters, but when it comes to DoW/DoM they are averaged between Rank 30-40s. Prismatic Llama got more players on DoW/DoM jobs at late 30s up to mid 40s then Metal Robot, so there is other competition to look out for ;)
I for myself don't bother rushing to 50. I'm fine with reaching 50 on like January(36 GLD, 32ARM, 32BSM), since there is no reason to be 50 at all and there prolly won't be until PS3 release, if not later. The only reason I'd go for Rank 50 is, that I can focus on other things like subcrafts or subclasses more <.<
