Should we make crystal scepter or Liandry's torment first?

Not the right board. Depends on situation imo though. Rylais if you need to keep distance. Liandyr if you have ability to freely kept engaged.

Probably shoulda went to gameplay for this...but generally I'd say first on heim. keeps most people in your turrets for longer, and helps you keep divers off you more easily. Think about the only time I'd run first is againt morg (as mid), cause she's just gonna spellshield your stuff anyway, so you may as well go for dealing more at once and breaking the shield to get more damage in.

If you hit your abilities, go luden then morello then zhonyas first. If you can't hit stun and W you want rylai 1st to play for turrets
