I disagree that the resting is a large downside.

The prep's duration (the one most people seem to use) is short anyway.

And it is unbalanced to our in a prep that's easy to get, unlimited, significantly improves fighting, and has minimal downsides for a large subset of the mud.

The imms removed sharkbait for balance reasons once that became well known (because I shared it ic with a newb who posted about it on the forums). That was harder to find, harder to get from the tougher mob, highly limited so easier to lose control of, stake out for ambush, etc. And then they put in this accelerate prep? It really needs to come out imho as it upsets balance and adds to prep inflation.
