Correct.
Injuries are not something you should play with.By the time you've
healed, chances are that at least half a year would have passed,
and your recourse would be nearly a year's time.
By that time, you should already be a vocationalist, probably
support arms, and a CPL.Not only that, if you have been downgraded,
your recourse would be a PES C recourse and that is quite easy and
relaxed.
