Which levels do you run in AL?

Hello everyone. I just started the upgrade from lvl 4 AL to lvl 5 . I know up from there i can do 2 trasmutations at the same time.
Which lvls do you run? Do you run those lvls to farm alkashards or only because they are the best in terms of material outcomes?

Thanks in advance.
