You mean like they already have been, over and over and over? It's not like they don't have up to 50% heal and shield power in items and masteries, or 2 really good shield items to add on to their on personal heals/shields, or the fact that they've stolen mage items in the update TO THE MAGES. Btw, before the nerf, I actually played Karma top with nothing but support items and a Rabadons after I got all the support items(subtract gold income item), and won lane and game. A few times. I haven't played it since the nerf but I don't think it'd be that much different.
