That's a good question, one Riot has trouble answering correctly on many of their items. In the absolute worst case, one way of implementing jungle items could be to make them work like, and require monster kills to upgrade them. However, currently Cinderhulk happens to be an amazing tank item while still only being really popular on junglers, so perhaps Riot already found their solution there.

The thing is, is balanced right now with the stats it has, as its pervasive AoE burn is a lot more powerful and less situational than the slows on. You're proposing to give it massively increased stats (+ 50 health and +25 armor) for just 400 more gold, which would make it a must-buy in top lane, which used to be the case a while back before Sunfire got nerfed to its current state.

I also think the MS-to-CDR change on would be an overbuff, as CDR is deliberately hard to purchase on mages, and usually entails a sacrifice in damage. Adding CDR onto an item capable of outputting some of the best raw item-based damage in the game would also risk turning it into a must-buy, even on mages who would not otherwise think of purchasing it (imagine what it would do to those who would, though, especially AP ).
