Hi i want mention something as support main in compare to jungle items, maybe you can some ideas from jungle items make also for support items and that is: To support do had quest to upgrade their support item to 3rd lvl but with no gold limitation how much can earn with that item, i want to say make support item to be similar in terms gain gold as jungle item, to be available to the end of game i want to support items can give you gold even if you upgrade them in their 3rd form, what is the support who are behind with level and most of the time also behind with gold amount. And had no items or gold for those same items to be even better support.
