2 Questions

okay i was wondering and people don't really tell me straight they answer with Korean silver > Master NA 

so first question 1 : Is NA easier than EU also would it be possible for a top 8 EU player in gold to go plat in NA? 

now question 2 : If im going to try get promoted to Plat on the EU server what is the best time to no life ? Is it on the start of the new season when there's space in upper division? 

Thanks for all the support day9 forums and day9 himself has got me from bronze to here :)
