Treat sunfire like a tank item, please

If we are going to have assassins play sunfire-bruiser, can we get an actual meaningful change to the problem? Sunfire is supposed to be an item for tanks to have some form of wave clear for laning phase and small damage for fights, hence its cheap price. The problem is that if we are going to have sunfire turned only into a wave clear item with increased cost, it is completely useless for tanks in this meta. Tanks are used for their cc in team fights, so with the increased cost of sunfire and range reduction, there's no reason for them to buy the item. Tanks don't have a typically good reason to split push. It is still useful for things like AD Fizz, where he lacks waveclear...but that type of playstyle is the reason the item got nerfed in the first place.

This sounds extreme, but I would like certain items to have class-based restrictions which go beyond the current melee vs ranged restrictions. This would solve the problem with assassins building sunfire and adc's building things like steraks as shown in the past. There are certain items that should just not be used on certain classes of champions which are shown to be VERY problematic.

On a side note: Riot once took a stance where they didn't like changes that made champions feel worse, but recently there have been a few changes that negate that stance. The sunfire range nerf and rammus's new self-slow come to mind. Thoughts?
