Piling is still possible, but with this scheme, it's not the dominating force behind the game

Bad placements are a disadvantage in the current scheme too, though. You have terrible luck if your worm
isn't placed near water for example.
In random turn order, basically there are turn cycles. In every turn cycle, all of your worms will have a turn.
So if you have 4 worms, when your first turn starts, the worm order is determined for 4 turns, for example: 3-1-4-2.
In each turn cycle, all of your worms will have had a turn. (so turn cycles like 4-2-3-4 aren't possible, because 1 hasn't had its turn)
After this turn cycle is over a new turn cycle will start

basically, this means piling is still possible. If you have 3 worms and your opponent has 4, you just have to pay more attention to your opponent's turns.
For example, if Worm 4 has a turn and then the next turn, it's Worm 4 again, you know a couple of things!
1) That last turn is the start of a new turn cycle
2) because of that, you know that the next 3 turns will be for worm 1, 2 and 3 and only after that will Worm 4 get a chance to do something.
If you decide to pile worm 4, it's still no guarantee that it'll work, but it's a pretty safe bet, but considering the original thought behind hysteria was complete and utter chaos, I don't think that's a bad thing
