User blog comment:XelNecra/Image and Role of Support/@comment-5514182-20121117034001

Character design is a big factor in creating champions. Riot made it clear that they wanted someone playing a champion without any previous knowledge of the game to be able to guess their role. Bulky characters are usually tanks. AD carries usually carry big weapons. Supports usually look... weak. Logically, an old man probably won't be the major damage dealer. On the other hand, if you create a guy with a giant sword and slap him into the support role, it won't feel right either.

Skill-shot supports may be an interesting idea. Supports with a high skillcap with high rewards. Lux is pretty much he only character with a skillshot support spell, but now that Nami is coming out, she's a support who can use skillshots to buff allies. She has some interesting tricks, which I'd like to see in new supports.

Also, the new Season 3 items will give supports a buff. There's a new item that has an active that both heals and removes disables from an ally. G10 items build into better items now, while still having the G10 passive.
