Hiya!

I haven't played this game for about 9 months so I'm kinda behind the meta and the going-ons.
I went onto the pvp and got demolished by fully awakened teams and that friggin moonchild.

What are the must-have toons and talis?

What should I spend my trooper and tribute on?

Should I save my awakening shards?

What units should I awaken?

What's the best way to farm awakening materials like star evo shards?

I'm not asking for handholding just some advice and pointers. Thanks
