Well, it is an Agh's scepter after all :D

On a more serious note, I think I went overboard with the Nunu one :x But I felt that the ultimate upgrades should bring more to the table rather than just a simple stats buff, as it would make getting the item more fun (plus makes for interesting replays).

Regarding the Jarvan one, I totally forgot he had another knockup >.> (shows my lack of gameplay with him). Hmm, maybe it would fear everyone caught inside for 0.5-0.75s?

Also, I think it would be alright for ultimates to have strong upgrades if the cost of the item was in the range of 5k and gave mediocore/weak stats (i.e. a very high recipe price), as it would be a lategame item then, making ultimates more useful into the late-game (those that have very strong CC might have to have weaker upgrades I guess).
