Ultimate (3250 RP) skins need a buff.
3250 RP is around $20-35 worth of money. That's A LOT of money for one single skin. In my opinion they ALL (Yes, even the existing ones) need these things for it to be worth it.
- Amazing model (if the champ has multipe models such as Sona had 3 different models/"colors"
- New/Improved animations (on autos, abilities, etc)
- Custom effects on killing blow -- (I was thinking Champions but I also found out Spirit Guard Udyr has this on minions/monsters too.)
- ANIMATED Summoner profile banner
- **ANIMATED Summoner profile Icon that gives a CTRL+6 option on ANY champion when you have it equiped, **(by CTRL+6 option I mean like when Worlds or the thing with team Fire/Ice was going on we had the team icons that we could use to taunt ingame.)
- Custom HUD icons -- The champion icon on the HUD is different as well as the ability icons.
Let me know if you have any more suggestions!
