Champion inspired by the Monster Hunter Series?
Something I thought about lately is a champion designed with the spirit of Monster Hunter in mind. If you haven't seen or heard of the Monster Hunter series from Capcom, I recommend. There are great weapon styles in the game, all of which can suit a LoL champ nicely.
The Greatsword known for heavy slow strikes The longsword, great for fluid, skilled combat The sword and shield a staple of mobility, speed, and quick offense. The Dual Blades, which harness the wielder's inner rage to shred the foe in a flurry of pain and blades The Hammer, while slow, deals TONS OF DAMAGE. The Hunting Horn, which provides healing and buffs with slow strikes and melodies. The Lance which utilizes a bladed steel wall approach. The GunLance (Or Shock Lance depending on your translation) which is slow, and bulky but offers range and melee The Switch Axe, which utilizes the striking power of a GreatSword, but allows for explosive strikes in Axe form. The Charge Blade, and oversized sword and shield that can be unified to create a devastating Double Headed BattleAxe with elemental power The Insect Glaive which harnesses long sweeping strikes and the telepathically controlled Kinsect, for reconnaissance and small attacks at a range. The Light Bowgun which does lighter damage, but fires flurries of bullet in a matter of seconds. The Heavy Bowgun, which trades speed for power and unerring accuracy. and finally the Bow, which fires a multitude of shots for any situation, from splintering spread shots, to painful piercing arrows.
Seriously, I would pay all of my money ever to see a champ wield monster hunter inspired gear and weapons. I have about 30 friends who would do the same. It's a game that is gaining a pretty substantial popularity with it's newest release Monster Hunter 4 Ultimate, and it's a perfect time to monopolize on that fame and attract some new players and maybe give some older ones a pleasant surprise.
