Isolation and single hex towns

[Hugmenot]

I think your suggested change is fine if you're talking about Local Isolation.

Note that after reading X.1 I am uncertain whether a stack of two or more units can be locally isolated.

The attacker must generally take some risk to locally isolate a defender so I think it's a reasonable optional rule that could be fun to try.

I doubt I would use the Strategically Isolated rule except maybe in a scenario large enough that each side have enough units to keep its frontage the width of the board or nearly so. That one does not feel balance to me but maybe I am missing the point. Hopefully Alan will chide in and explain the rule in more details.
