ok, i think the question is pretty clear
will any1 help?

When the new expansion comes out, I'm sure people will be happy to let you know where to train after 375.

then why there r patterns that require a higher skill than 375... strange

Examples?
There may be some in Thott or in Beta releases, but I do not recall any recipies in the commercial game which require >375 skill...

375 is maxed out

you need to make 375 (PSUP) push-ups to skill up
