Actually decided to play ranked all day today, went from 1400-1496 elo. =P
Jayce is a ranged AD carry/Melee Dps champion capable to dealing TONS of damage, both from afar and close and personal. Jayce has the ability to adapt to many team comps, lane opponents, and roles for the team. Jayce has his ultimate at level 1 like karma, however unlike karma he still can RANK his ultimate at the normal levels giving him nice little bonuses. Jayce has amazing harass in lane and is capable of killing many enemies in just 2 combos of his harass.
Hextech Capacitor- Jayce gains 40 movement speed and ignores unit collision for 1.25 seconds each time Transform is cast.
This passive is nice to jump into your combos, or keep up in the fight as your switching your weapons around. In lane the ignore unit collision part is VERY helpful as you can switch weapons and run straight at them or switch weapons, run through them, and hammer them abck.
To the Skies!
