From now on let's not call eachother wrong and just say why we disagree. Because basically that's all you are doing. Example:
'Ninja can learn Ice3.'
That is wrong. Feel free to correct someone in a polite fashion.
'Ice3 on a Red Wizard is useless.'
This is an opinion. Calling it wrong is the same thing as saying you disagree. Please use this type of phrasing in the future. Feel free to disagree and say who you do, of course, in a poilte and courteous fashion.
Also, don't double post.
