About the only thing I agree with is introducing different sweat colors (types). Think of it this way....
ME is considered ammunition for Mind Force.
Weapons require different type of weapon cells, why no the same for the various Mind Force chips?
Pink Sweat for Healing/Reviving
Blue Sweat for Teleporting
Red Sweat for Nerve Blast/Firestorm
Yellow Sweat for Focus
...I think that's all of the present chips
And of course the generic Green Sweat that can be refined to use as 'all purpose' sweat. This would help with the introduction of new chips (if that happens in our lifetimes

).
Just my

on sweat evolution.
As far as price goes.... it will always float around .55 pec per bottle. What it is 'normally' sold for is solely up to the sweaters.
But keep in mind all the
FREE heals and focus you receive at Nea's and Swamp Camp when you decided you refuse to sell at a cost-efficient rate.
The 2-5 Healers that are out there skilling for 5 hours a day will quickly become 1-2 Healers every other day!
