I would like to hear your opinions.
This suggestion has both advantages and disadvantages... the main disadvantages have already been described...
And among the advantages, it should be noted that the monster balance will improve – that is, it will be possible to see the real confrontation between castle troops – and not which castle develops faster or more efficiently on balanced or unbalanced maps!
In other words, this ban will allow us to get closer to playing on "fixed" maps, but with elements of randomness... (I've seen a tournament somewhere on a specific template, but objects like "canned goods" were prohibited, even for gaining experience!).
I support this suggestion only if this ban will be used in the rules for a specific tournament(s).
For general rules for "rating" or other seasonal tournaments, this point is, in my opinion, unacceptable!
