The rules for HotA tend towards completely eliminating verbal restrictions, especially those that are difficult to monitor. The rule regarding repeating a turn can only be reliably monitored if the player is streaming. And there is also a reverse problem – if a player performs worse during a repeat, there are usually demands to allow another repeat. To avoid all of this, the rule "the player is not obliged to repeat a turn" is used. Yes, sometimes it may be unfair, but its simplicity and the lack of a need for monitoring more than compensate for it.
