Hello, friend. Neat. I really didn't like that Blood Transfusion, a healing ability, had such a powerful offense/utility effect added in the form of Energy Regeneration. This is the very reason that I split the two. I gave Improved Painkiller shields because of the idea behind the ability - it blocks pain, and shields block damage to health. I wouldn't necessarily mind giving it Armor instead, I just felt that a different spin on the concept would be neat. As for Improved Adrenaline, the additional sight radius is intended to benefit scouts - their primary job is to go fast and look at things, ergo, Improved Adrenaline provides bonuses to both. I wouldn't be opposed to changing it to something like Jump Cooldown if that would be more appropriate. There are some issues with it as have been pointed out by other users (primarily Duck), but I appreciate your feedback and I'm glad you like it.
