I can honestly go jungle or adc, so I'll list 3 adcs and 3 jgs if that's cool, if not...sorry.

Availability: Weekends, Mon, Wed, Fri
Top 5 champs and why:
Cait - I enjoy the early poke in lane, and the fact that her skills aren't needed as much, her autos do a lot of damage.
Ashe - I know she doesn't deal the most damage, but I love her utility. Especially against an Udyr, he can't chase or run as much as long as you can kite with frost, and I think this makes her very valuable even if she doesn't get fed early game, she'll always have her slows.
Vayne - I enjoy her stacks and even her own utility. I practice her tuck and comdemn into walls all the time, or even trying to go around champions and comdemn them back into my turret, or away from me if I'm low.
Warwick - I like his sustain in the jungle, though he's banned a lot now.
Volibear - I enjoy his mobility, I build him tanky (all of my junglers really) that way I can give the kills to my allies, I'll always have my jungle camps to get exp and gold, it's more important that those that do damage get the kills. Voli's slow and flip helps with that.
Xin Zhao - He was my first jungler and I still love him; w e q, throw an r in there.
Strengths: As a jungler, and even as an adc if I have the gold for it, I always buy wards - I don't feel anyone shouldn't by wards especially with the limitation on wards now. As a jungler I try to build health and armor as quickly as possible to get those -secured- tower dive kills, and I do favor Voli and Xin, that way I can gank pre 6. As an adc, always looking for the plays and always looking to go all in.
Weaknesses: Going to be honest - map awareness.
