Haha true, right now there is literally no pro that's playing dazzle support. I'm guessing in a couple of patches valve will force him back into a support though
I should have made that more clear, my bad! Core heroes (The hard carry, midlaner and offlaner) are the heroes that take last hits (minion kills and through that earns gold) at the start of the game (and usually throughout the entire game as well). The opposite of core heroes are the support heroes (the hard support and soft support), who don't take last hits at the start of the game and are generally a lot lower in networth and gold throughout the entire game.
