Note it dose not actually lower ranks when hit by the first two degrees, that would require Weaken. This is important because it would not slow you down if you had flight (just give you a penalty to checks made while flying) or remove immunities

This is just how it is built in the Meta power profile. I see no reason to require broad or simultaneous to the affliction.
Remember that as it stands Impaired/Disable just gives you a flat -2/-5 to ALL checks so its not that much different.
Affliction + Cumulative: only cost 2 p/ per rank but it only implies a -2/-5 penalty to action that involve your powers it is only if you get a 3rd degree that you make them completely powerless
If you want other option of doing the same thing
Nullify (+ broad + simultaneous) cost 3 p/ per rank but turns off All powers of a given broad set until the opponent next action. It is more costly and time wise is very limited but can be amazing.
Weaken (+ broad + simultaneous) cost 3 p/ per rank lowers ALL powers of a given Broad group by -1 pp per point of success but they return at 1 pp per round. My favorite way of doing it .
Over all using affliction is the cheapest way of doing it so I could see you wanting to imposes some sort of +1p /per rank to bring it up in line with the others but to be honest the problem lies with nullify and weaken not being balanced against damage and affliction not the other way around.
