Hey,
it seems to me that shoving is bugged (or calculated very different than it should be according to the PHB).
Or can someone explain to me how enemy goblin casters can reliably shove my character (str 17, proficient in athletics) off the wall while I'm standing 10-15ft away from the edge?
I mean, if a minotraur or maybe an orc fighter would shove me that far, I would understand it, but a simple goblin caster should fail most of the time and only manage to move me 5ft if he gets a lucky roll.
