Yeah I understand that it could sound complicated. But basicly, you have 4 kinds of stacks: One for each kind of essence, and the 4th one is for the ultimate. I do not know if you ever played Karma, but to use an Enhanced ability you need to have at least stack of mantra up, which is consumed. This is only to prevent people from constantly spamming Q Q Q R Q Q Q R Q Q Q R with no cooldown. I do realize that, however, having 1 sec global cooldown on all the rest sounds rough, and that's why there is an active. It shouldn't be as strong as his ultimate combo, but it is there just in case you run out of mana or you simply don't have time to combo up.

However, it's true that having no cooldown on Q W and E would make this guy a bit more fun, and having more than just 4 combinations as well.
