Remove/nerf/change menders + hypospray suggestion

[Goat_Real]

If we were to switch back to patches, don't patches have the effect of making medbay's medicines less effective due to patches only apply half of the reagents that are in the patches? This would basically force the playstyle of beaker splashing as you'd be wasting medicine and time, due to the inherent slowness applying medicine via patches, if you were to use patches.
