After that, depending on how much you can play, you should expect about 1-3 weeks of dungeons/lfr farming until you get invited into random raids, and from there it will depend on your own initiative to get into a raiding guild.

for comparison: with RAF, 1-80 takes 10-15hours, and 80-85 usually takes 2-6 hours depending on wether you use endless farm spots with a farming group or not :O
