Missed Opportunity for Santa Ornn IMO
Passive changed to Ornn producing a sack full of gifts and rummaging through it until he pulls out a gift wrapped box.
Q changed to Ornn rolling a quick series of snowballs forward that form a snowman at the end of the line.
W unchanged
E unchanged
R changed to a giant reindeer with the SFX of sleigh bells
Recall changed to Ornn boarding a sleigh drawn by his ult reindeer then taking off into the air before dropping back down into the fountain.
Homeguard animation changed to featuring Ornn running with a giant sack of presents slung over his shoulder.
....Or something.
Seriously, this guy hasn't been given a skin since his release and much of his deal is gifting his allies. This could have and possibly should have been done.
Maybe next year, RIot...maybe next year.
