Coz you had to reply in an inappropriate manner. Can you keep it clean and make valid reasons. And those 5-8 people you are talking about may have been here longer than you here in the server and the forums, compared to you who has been on the forums since 3-1-2015(scroll over the name FYI), may have read the suggestions for wizards and would know what they are talking about. As we have read the various reasoning of players, those who actually play wiz in a high end level.
On topic:
You just focused on 1 way of beating other players, which is to spam your skill head on. Its pretty similar to a previous suggestion which was to make GTB reduce magic atk instead. Alot here have already said it, why would you atk someone with magic knowing that you would only do less of it compared to what you could do with a specialized stave crasher gear? We should suggest a pneuma-piercing bow or arrow while were at it.
