Hmm a great way to escape %20 drop on qualities as well. Just pump up a specific skill with same drill all the way. Well %20 drop will certainly happen if promoted but mutant will remain mutant after it loses from %3000 - 1/5 = %2400

Hmm. As suggested by many , a cap should be integrated which is limited by lit skills' overall if not all. Second of all current mutants should be reformed to reflect that overall which means those mutant skills will return to 50 or so at max.

Finally, drilling the same training set should have a diminishing effect on training's outcome so that people would not be willing to initiate such regimes at all.
