If I understand this correctly, it is made to fix the so called Hallifax Hammer Issue. But this strategy as far as I know, do not involve the governor to a greate degree, so why limit it?
One of the methods of executing HH under 1st ed rules and the only method under 2nd edition rules involves governor greatly.
I'd say the best way to avoid the HH strategy is to play with 2 ed rules, and then simply dont do a HH as brit.
Now that was random. How about playing with 1st edition rules and simply not doing HH? Does it not work?
The HH strategy is very specific (atleast when you use 2ed rules), and need to be started at the first turn, taking Halifax.
This is not true. You are probably talking about a very early version of HH strategy, which evolved with time.
