I want to get rank 40 asap how should I do it?

Just do challage logs every week, so you get around 2k extra xp every week(depends your rank). Wolves den queue seems 2 be impossible after 2.3 so I suggest doing only frontlines.

That would imply they are in their data center's winning GC. I'm in my data center's constantly lossing GC, and I've had weeks with 1 win and 38 losses, making the 3 frontline win challenge impossible to complete, and the only win I got was when i was lucky enough to get an 8v8v8 match and Maelstrom and TA actually had to work instead of just dumping 4 healers on to a point and over healing everything done.
