hi guys,ive been playing games my whole life, all 15 years wasted on games

.
i live in South Africa (

), and with the experience ive got with games, i want to make a suggestion.
You have generals,which control(mostly) the armies. Assassins deal more with pumping out damage.
A class i would love would be called mystic.this class would be dedicated to supporting the troops.
Like here:
He can erect towers that can cast beneficial spells.Each tower can be equipped with like 2 or 3 spells. on auto cast.
if he decides to go to the battle, he can harass the enemy troops by casting debilitating spells on them.
the other mystic can like, erect a building that periodically raises a zombie or skeleton from a corpse.
What do you think?
