I'm curious for which champs do you like more for the different position in LOL, for me they are:
ADC: Ezreal, Corki, Draven.
Solotop: Jayce, Darius, Jax.
Jungler: Lee, Hecarim, Nocturne.
Mid: Khartus, Twisted Fate, Lux (Soraka is very nice mid too)
Support: Lulu, Sona, Soraka (maybe Nami too?)
Those are my favorites, for ADC i like champs that has nice poke and escapes, for Solotop i like big damage, for Junglers the mobility and clear time plus providing a nice gank, Mid i like champs that has a nice CC, preferibly with silence, although damage wise Brand is better at spamming spells and does crazy damage, but the CC's are invaluable and finally for support champs who can protect and enhances the AD carrier.
I'm curious for your top 3 champs in LOL and why =)
PS: English isn't my mother language so srry for any bad written word.
