This happened earlier. I, obviously, am HalcyonGlaze and I was playing Jarvan IV, aka J4. Had a jax top, who, interestingly enough, counters J4 if played well. However, he fucked up early and I never let him recover; it was demacia all the way down to chinatown. And then I proceeded to dominate the top jungle as well as my lane, then dominate their middle and they gave up when I walked right into four of them, a weak teemo who was insta-gibbed by my ult (Jarvan jumps into the air and makes an arena of stone that no one can get out of for a few seconds + it does damage to everyone involved when you do it), then I beat the shit out of the full hp kennen inside, then when sona and jax tried to gun me down, I speared jax back into oblivion and chased sona. However, sona made it away. I yelled DEMACIA at them in /all chat and they were were like >:[! So yeah, was pretty game over for them if I can solo the majority of their team and get away alive.
And in case you were wondering about the Demacia, J4 is the prince of the area called Demacia. A bunch of the champions in LoL are from Demacia and they all tend to yell DEMACIA when you trigger their strongest abilities.
Some Demacian goodness incoming:
^ Garen, another Demacian guy. His thing is 'spin to win' because one of his moves involves spinning very rapidly. =P I can't get it to link quickly and I can't be bothered to actually code it in myself. Not today, no sir.
I can't be bothered to not be a geek atm. =o
