You could carry someone on your back, and his/hers ep's would not
get reduced when the carrier moves. The carried one is as vulnerable
to any external influences, and the carrier cannot hit or defend.
The carrier loses ep's with the ratio of normal+carried_race_size/10
while moving.
A bit useful when you have loads of ep's and youre running away
from something and mages/others who are not used to hiking get
exhausted and left behind. Or when moving from area to another,
and there's no tree etc... healer could cast BOT, hop to tank's
back and off you go .
Optionally, if the tank is big enough, he could carry some
smaller groupmember over the water perhaps? (I know WW is
invented & implemented but nevertheless)
