In our tests we used 10d4 x 10 feet starting range if both combattants were ranged. If one (or both) of them was melee, we would use 2d4 x10 feet. Characters were on a plain. No hills, sunny day.
Seems kind of close. In any event, you are in distant counterspell range. Given distant and subtle I'm not sure how the wizard is getting any spell off while the sorcerer is getting spells off.
In close quarters testing (a 60 x60 room), all casters were failing save the f***ing diviner. The use of contingency in close quarters was saving the bas***d's asses more often than not. Those three dices are real killers.
I do expect the diviner to beat pretty much everything else.
How exactly were you using contingency?
