Horizontal or vertical approaches?

Hello you all,

Fellow player seeking for advice. I’m a F2P player with 87 days played. Until now my approach was to build my roster horizontally, but in face of recent changes to paragoning was wondering if it make sense to start investing vertically too.

Right now I’m sitting on 19 S+ units (Hewyn and Antandra are maxed copies, missing acorns only), 4 S (Shakir, Vala and Sonja missing 2 copies; Caroline missing 1). Damien, Kruger and Sinbad almost M+.

Should I start pulling for some paragon copies of LM and Odie, for example, or should I keep pushing a more horizontal approach. For example, in my wishlists should I keep LM there or trade it for Granny in normal banner and Alsa in epic banner.

Any suggestions are welcome

Ty in advance
