Support Veigar, a good idea?
So I have been playing veigar for the past couple of matches, and why is he not played as a support? He has a good stun, does not requre a lot of items and has great damage potiental. I understand that he does not have a shield or heal, but neither does human torch over there, so why is brand played as a support but not veigar? You could even say that vegiar is better at being support than brand seeing as he gets ap from just hitting enemies with his spells, making him less item dependant than brand. His stun is also a lot more reliable to land than brand.
Now I fully admit i am a dumb noob who is bad at the game, so please do point out any issues with vegiar support. I am here to learn.
Get 45% cdr and you have a really strong CC bot with decent damage.
