I go a tankier shapeshifter comp which I think is the way to go.
My composition looks something like this (with the bruiser ? class being able to be swapped with other champions) The point of it is to burst/cc/tank all the damage that your opponents dish at you
I find Shyvana to be more like an ADC once she transforms (I take dragon for more damage and resistance against magic comps)
Shyvana Dragon/Shapeshifter
Sol Dragon/Sorcerer
Nidalee's here to activate the shapeshifter buff + wild and gnar for tanky-cc. Shapeshifter buff + bruiser buff = tankiness for days :3
Gnar Shapeshifter/Wild (ignore yordle buff)
Nidalee Shapeshifter/Wild
She's just here for dps/to activate the wild buff
Ahri Sorcerer/Wild
Warwick Wild/Bruiser (I'm forgetting the term for him)
Cho'Gath Bruiser (Ignore void buff)
You can switch out the cho'gath for another sorcerer instead but I prefer the tankiness buff from having two bruisers (I don't run elise since she has little to no synergy with the other shapeshifters and comes off as a little weak sometimes). Although they can and will get screwed over by glacials (but what comp doesn't?)
