It is clearly the intention of a leveling system to slowly advance in levels until you reach maxlvl. If there is a way to skip that and be maxlvl instantly why waste the precious development time for creating the leveling system in the first place?
well yeah... and here we have the problem already. either the intel bulletins/unlockable commanders are "cheating", since they give an unfair advantage (no matter whether you aquired them via "legit" grinding or by loading savegames), or nothing is imho. if i play as a lvl 1 vs. someone with all unlocks already... is my opponent cheating? no, he is only using legit means against me, even if it means his chances of winning the game might be higher. i don't think using a script to unlock the same options that he has at his disposal constitutes cheating. at least not moreso than introducing/using the unlockables in the first place.
