I've played a couple characters to level 10 in AoC. I have not seriously looked for the following but they have not jumped out at me.
1) Follow - Without this there will be NO multiboxing AoC
2) Macros
3) Fun

In addition the solo quests are solo instanced. Which means that you won't be able to get any help. Although only playing to level 10 I don't know if this will be an issue after.

Things AoC does have:
1) Nipples
2) Interesting melee.
3) Mounted Combat - This is only what I heard... I have yet to see it.
