just asking what you think

My favourite is Brand

same Brand
maybe not the strongest, but i have orgasm watching him ulti xD

I play morgana or orianna mid
both are fun champs, but orianna is kinda hard to play :P
anyway:
there is no best champ for mid. it totally depends on the enemy champ + player skill you face.
some say, kassadin is the badass
other say, cassiopeia
or karthus...

well i you want constantly hit your enemy midder without any respond so take xerath, awesome midder, but sertanly not as good as brand or other mages in the late game IMHO

ryze

cassio

The best sustained DPS in the perfect situation: Anivia
" In a moving team fight / chase: Ryze
Early game dominance: Cass, Karthus, Anivia (Q/E or just the power of her egg)
Level 6 onwards, killing enemy midder: Brand, Annie, Morgana
Utility for your team: Anivia, Cass, Annie, Morgana
Lategame Initiaters: Karthus, Annie (Stun Tibbers), Brand (Provided he has pre-landed a q-e combo), Gragas, Ziggs, Galio, Morgana (Zhonya's)
Anti AP Mid: Veigar
Zoning: Ziggs, Brand
Pushers: Morgana, Galio, Gragas, Sion, Morde

Some people weren't included such as LB, Sion, Kassadin, because they have pretty hard counters that would render them useless. Annie is easily countered but her ulti is invaluable.

Not the best, but my favourite, is Katarina, because she is the most unique mid champ ever.

fizz ;D
