Advice on Rank up Sequence (who first followed by __)

I need advice on Rank up Sequence based on Champ availability and Game progression.
I regularly participate in Map 5 or 6 in AQ
Elders bane but stuck in 6.2.6
Completed V3 and V4
Who do I rank up in terms of sequence based on the champs that I've got.
Thanks in advance.
See my roster below.
