I am wanting to start get back into ranked, but I have no idea what champions are good in this current meta. I main Adc and I need a few champions from each role so I have a solid base of champions/picks for ranked. Any help would be nice, thanks :D
In my opinion
Adc: graves,sivir,Lucian, jinx
Top: Irelia, gnar, Maokai, sion, ryze
Mid: xerath, zed, Katarina, Cassiopeia
Jungle: nidalee, fizz, Sejuani, vi
Support: (not very good support so probably an inaccurate tier list) Janna, thresh, blitzcrank, morgana
Keep in mind that your best champ is better than any champ on this list and these are not must picks.
Keep in mind, it all comes down to you and your skill level with a champion. But these fit the meta the best currently:
Top: Maokai, Lissandra, Hecarim, Sion, Wukong, Irelia Mid: Ahri, Katarina, Annie, Viktor Jungle: Sejuani, Amumu, Hecarim, Vi ADC: Lucian, Corki, Graves, Jinx Support: Blitzcrank, Janna, Morgana, Nautilus
Be aware of certain picks that are mechanically intensive such as Ahri, Zed, Lucian, etc. Then again, the best champs change almost every patch.
So have this: http://www.nerfplz.com/2015/03/2015-champion-tier-list-solo-queue_27.html
IMO
Top: 
Jungle: 
[Insert tank junglers here]
Mid: 
ADC: 
Support:
