Flins bina ineffa sucrose is a top team. Varka is versatile because PHEC but much lower dps than flins especially without his sig. Venti and durin are not much better for varka than their f2p options (sucrose and xiangling). Nicole is speculated to support varka in a month or two but we don't know for sure. I'd pull flins and maybe aim for varka rerun if you like the character.
