The Soul Burn + Mayelia combo was an intentionally changed feature a long time ago and only is oppressive due to a dullahan's interference resistance.

Interference resistance is mostly there because without it, dullahans very quickly turn to this loop of being unable to do anything when faced with FP Drains, and there's no real balanced way to take care of that currently. Though I think the potential for 100% interference resistance can get a little nutty a little fast, it becomes the most egregious when a dullahan has a healing buddy.

What would your solution be to the Turn Order shift with the stun? If you have an opinion on it?

Its not exactly unintended, I mean when a dullahan misses a turn while its slower than its opponent it is effectively being double turned, the issue is only pervalent because it can wildly fluctuate the turn order assuming both sides are even, its hard to fix it necessarily because you are just removing that person from the turn order, there's no special tag that causes them to take their turn and make it right.

I guess the most jank way I can think of fixing it is to have a soul burned unit be able to take its turn, but have everything except end turn disabled.
