As they say you can't have everything. You wanted better drop rates, so you got'em but the bosses are now tougher to compensate.
Thats like saying to a blind person that "We will cure your blindness" and put 2 donated eyeballs in he hands and tell him "goodluck"......

Heres a thought " How about improving something for once and not make something else worst at the same time. Improving one thing but making something else harder for the same item is not improving anything, plus I wonder just how much on an improvement they really did to the relic drops...maybe it went from .002 percent to .003 percent.....oh but it still would be an "improvement" now wouldn't it....
