This needs to be changed, it makes absolutely no sense as it is currently set up. I have stated this before but this rule benefits gangs who can not (or choose not to) grow as fast as others. Right now there are multiple gangs above ours that are clearly weaker than us but since we have about half the amount of available targets as them (plus I believe some of the top gangs can't touch them but can with us) it is proving extremely difficult to pass them for experience. Several of those gangs above us actually meet the "too weak" status so we can't even attack them ourselves which is ridiculous since they are according to the rankings "better" than us.
No matter the purpose (if someone can please explain to me what it is) this rule does not work. As I have stated before I could create a new gang, keep only 10 players, never upgrade, and we could become a top gang just because any of the good ones won't be able to attack us
There is already a once a weak attack rule against a gang so I see no reason for the need of this rule
