I got 5 ex out of 46 boosters, Blaziken x2, Sceptile, Raikou & Suicune
Although these did come from 4 different boxes (1 with my sealed deck boosters, 1 with my dad's sd boosters, 1 with my prize boosters (7) and 1 with my dad's prize boosters (27)).
why would this be bad? There are 8 ex's in the set. There are about 12-14 Holos. I think that 3:9 is pretty good, even though it screws up my old ratios (I always assumed 4:8) because it gives us more of the Holos, and less of the ex's which are supposed to be the rarest cards around.
Bullados, as much as it pains me to say this...I agree with you.
EXs should be more rare. 3 per box makes it a challenge to put a set together (3 boxes!!!) which makes the EXs as rare as the rev holos (3 boxes for a set of those too!)
