Like in most real friendly matches, more than 3 subs should be allowed. IMO we should get as many subs as are possible with the number of advance instructions (AI) that are available. Currently this is 5, but admin has indicated that additional AIs may be coming.
While I'm on my soap box, it would be nice if each AI offered the opportunity to make up to 3 subs, rather than just 1. This would offer greater versatility with the AIs that we do have in competitive matches. Besides, if there were more substitution possibilities per AI, there would be less of a need for additional AIs.
