 No - as you can point it, apply it to certain units etc. Perhaps if the possibility of 2 leaders is too much (orks, infantry horde, assualts, lots of leaders ?) drop the commissars for free and make them a paid for upgrade.

So, now we are changing how the IG Commissar rule works? I not inclined to go down that path.
Ok, quick ruling here to keep us moving:
Iron Discipline 
Any formation containing at least one unit with Iron Discipline will require 1 additional blast marker beyond the norm in order to break. In addition, when a formation with Iron Discipline attempts to regroup, they will ignore the -1 modifer for troops within 30cm, regardless of broken status. The formation may be suppressed as normal.
Lock 'er down John.
