User blog comment:Jens Ingels/The support item rework (suggestion)/@comment-5035765-20150502085046

giving income items the ability to generate wards gives them RIDICULOUS cost efficiency

not only does it directly give you money, it also saves you a bunch of money buying wards

even for support items, this is just absurd

though i will say that i personally often only upgrade the income items all the way for their actives, not their stats (most of which tend to be just as easy to get from other places...)
