Heroes 5.5 WarGame Edition - Tactical Edition.

That's true, but following that logic, battles also "added slowdowns" due to reduced speeds, albeit to benefit tactics. The question is what is more valuable. Plus, consider that the length of a hero's turn will be significantly increased.

However, Dirman writes to me in ICQ that technically it's impossible to do this, to nullify or reduce a turn when heroes meet, because the event isn't triggered (unlike meeting neutrals). If that's the case, the concept will have to be revised in any case.
