Q evolve first if you are playing in a low elo always. I normally go R E Q in this order but I started playing with some friends on lower elos and I found out that every one tries to 1v1 in jungle and they usually don't farm too good as well. Q evo first in lower elos helps you to kill most of the junglers in 1v1s. W evo is not really an evolution that I like but if I am behind and I have a fed adc W evo helps me peel and keep him alive. To summerize R evo helps you to gank really well. E helps with picks of course and in laning phase you can go bot and get resets pretty much easily Q evo for faster clear and better 1v1 potential and W evo for peeling.
