Machinist need buffed

[Shneibel]

I think hyper charge debuff stays up for about 20-25 secs if I'm correct, not to mention how you can double dip into the debuff and mana ticks and get the most out of HC.

yup, as soon as the debuff is on, you can turn on promotion for a few mp/tp tick and turn off promotion again to refresh the debuff. I have never get into situation where I need to do this (hopefully never)

The time is about right, depend on turret's attack timing
