Time and time again I've seen it happen, and yet no one from the admin team except a very small, very experienced handful enforce this rule - some even go as far as to break it and then unknowingly spread it to other regular players who then repeat the same patterns of play;
On these examples specifically, Stinger AA on Muttrah does not pose a threat until East City, there is 0 reason to attack it at game start - quads don't pose a threat until South City... This is not Pavlovsk where most AA can actually see 90% of flags where ever you go, and it makes perfect sense to take them out so that trans can do its job.
Imagine every time I had the opportunity that I took a screenshot - I would have more than 50 pictures for the past 2 months alone...
Please enforce these rules, as no one wants to sit 5 minutes on empty flags just capping.
There are of course exceptions that one can clearly identify based on map terrain, flag positions, enemy reinforcement routes, map difficulty, etc. Use your brain to see and determine if something is detrimental to your team. Would it be fun if you were placed in that position?
