Ascencion Question

[Gotejjeken.1267]

Since I know no one who does sPvP I'm trying to get the Ascencion but solo.  I can do all of the achievements except the multiclassing one--my mind is just too engrained to ranger.  

Question is, what's the best time to try the profession achievements? I'd assume not during a 3v3 / 2v2 mini-DM season as seems all the tryhard builds are out for these? 

My current thoughts are wait until just a normal season and shoot for bronze, then hope I either learn the class or the other team is bad enough we win?

Perhaps do the placement matches for the next season on new classes. If you win great, if you lose you'll tank your rating and you'll have better chance of winning when placed.
