The Optimal way to play the Sona rework isn't fun.

To make it through laning phase, because her stats are even weaker ad/ap/poke/defensive its better to max W first and go Coin for lategame with the frostfang nerfs and the nerfs to her poke. Which just makes Sona a healbot, and not really even a healbot since it's only mana efficient to cast the spell when your ally is half health. You need coin to position for lategame since her E spoodboost isn't strong enough of a speedboost to catch up to allies. Her build path is more limited than ever, you NEED 40% cdr and about 200 Ap to feel useful. Why the heck did they let this off PBE?
