Is there a Req Limit?

When I say Req Limit I mean is there a number amount of a certain Req you can get before you can’t get anymore? If there is what is the number? If there isn’t, what do you think it should be? Personally I think it should be 100. Once you hit 100 of a certain Req I feel it should start giving you other Reqs that are not maxed out.

I think the max is 200. Not too sure though.
