User blog comment:Bovell/Color blind assist option for Modern Warfare 3. Killstreak system reworked./@comment-3465836-20110708235710

maybe reworked means it simply works better, like it was from cod4 to mw2. maybe now they have more then 3 killstreaks? or maybe higher ks unlocks with more kills with that killstreak to show that u have enuf skill to use the next ks and to discourage boost
