I've been playing quite a lot of Magus on KN, but now stuck due to the new pets mechanic (which i don't fully understand tbh

I want my Magus to be RvR solo-roamer, kiting, dots, pugs - and be as much mobile as i can (yes, i know Magus is not the best mobile class).
What should be my demons playstyle? My build will be common 1+2.
1. When it's better to use Pink Horror? Vs whom? Vs ranged enemies only? Or vs specific classes?
2. When should i go for the Flamer? Vs melee? How do you manage Flamer? Compared to vanilla WAR, now Flamer allows you to cast Surge of Insanity, Warping Blast, Rend Winds, Pandemonium while moving (and what about channeling abilities like Indigo Fire of Change? Also?).
What's your General Kiting Plan after the patch?
- start attacking from 100ft;
- when enemy is approaching - kite (run away from your demon) and use all these skills with cast-time as long as you have buff from the demon, which is decaying;
- when the buff stacks are close to 0 - Resummon demon to be able to continue kiting thanks to the Flamer buff?
- then i continue to kite. Once my buff is close to 0 again - should i have Chaotic Attunement tactic ready to instantly resummon demon? Is it really useful?
What should be my general goal when fighting vs melee? Kite and try to have stacks >0 as long as i can? Or it's better to stand still/kite in the small buff range, always having x8 stacks to maximize damage?
I would appreciate any help on fully utilizing new demons potential

Thanks.
