I'm glad to see you have such specific information on exactly how the old proc chances where implemented, and are thus able to make this perfectly informed statement about how removing them will have no effect.
Lol, devs more likely knows what are they doing. Besides - there was information that because of some changes these sets will don't bother server with their proc, so they will be more neutral like non-proc sets. So, there is no way to increase stress on servers
