I’m semi-new to valorant and I’ve unlocked most of the agents except killjoy cypher astra and harbor. Should I unlock these agents because I think they aren’t very good and I would rather unlock agent skins?

Ever since the right click flash got nerfed, I've been struggling with the left click and essentially been using it like a yoru flash, and trying geometry and bounces, but I've not really been getting people. Any advice is appreciated.
