Another thing is that the chance of success itself doesn't seem terribly high either. It is worth remembering that rage gives an advantage in strength's checks (it should facilitate throwing enemies).
On a stream, even in active rage, the chance was quite low and amounted to around 65%.
The highest of what I have seen is 70% and this is only in the case of very light skeletons.
The fact that the percentage chances don't change while raging is evidence that Throw is based on an attack roll, not a strength check. Which is it's own problem. But it also means that having Advantage on attacks - not that hard to get, and more easily obtainable for non-barbarian classes - will turn those 65-70% chances into 88-91% chances.
And more importantly, the % chance displayed is the chance to actually hit the enemy with the thrown enemy.
It seems to be a 100% chance to pick up and throw an enemy. (basing on what I saw on Stream and @Niara's Throw Wizard investigations way back).
I watched the stream again and in fact, when Swen tried to catch the goblin, it showed a 65% chance. This means that it is definitely not 100%. In practice, it looks like there are at least 2 checks (one to catch and the other to hit another enemy).
A little testing would be nice. Unfortunately, only on Thursday I will be able to start it. I bet, however, that the enemies roll athletics or acrobatics (probably both, depending on what is higher)
As I wrote in the previous post, the enemies weight limits the effectiveness of the throw quite significantly, which means that if the character does not have a really high strength (20 is probably not enough to throw an average humanoid at a reasonable distance), it is unlikely that it would be worth wasting your action.
