How many people play descent with the same alternating turn structure as Imperial assualt. Meaning instead of all heroes going than OL. It would alternate 1 hero than OL, 1 Hero than OL, etc. until all heores and OL groups have gone.

I tried it once and it didn't work very well.

Part of the issue is that certain things happen 'at the start of the OL turn' or 'at the end of the OL turn', which can cause issues when altering the round order.

The campaigns are also intended to be balanced around the turn order, in many cases an open group or monster group will start in the same room as the heroes entrance. Usually this means the heroes just waste one round slaughtering that group before moving forward, giving the OL time to move the other groups into better positions. If you alter the turn order however, you are going to see some dead heroes on round 1, after one hero gets to move, and the other 3 get fire breathed to death by 2 shadow dragons.

Great topic and I'd like to share my feedback as it became a debate with the group I play with me playing the OL and 4 H's (heroes') and as Silidus stated there are some issues that need addressed.

First Issue Balancing - The games play very differently depending on the number of monster groups the OL has. The more monster groups he has the more sluggish his monsters seem. The less OL monster groups the quicker his monsters become. Same for hero's, the more hero's the slower they become the fewer the faster they are. So you have to address this which leads you back to the one turn per side hero/OL and then round end.

Second issue Rules - You would be making some house rules for sure.

Third Issue - Drawing from the OL Deck: If there are 2 OL monster groups and 4 heros the OL would be drawing twice per hero round because he would have two rounds per one hero round. Inversely with 2 hero's and 4 OL monster groups you would be drawing at half the normal rate from the OL deck.

It is more realistic to have each hero and each OL monster group make an initiative roll then play through the turns based on the rolls and after the last turn the round is over.
