thoughts about doors

[gedads]

Hi, i was thinking about the door removal decided after the CN bug(that's the only camp where mobs are stuck) .
In retail, when you ride a chocobo in batallia S , rolanberry S, gates are opening once you're nearing them (while the player running needs to click them).
in the npc_list, doors are either lcickable or not (flag 4099 or 6147) and shares all the same model 0x02000...
i was thinking that if instead of removing every door it could be possible to block mobs regarding those flags, 6147 would block them 4099 would allow mob to open / go through (99 percent of the time they go through, the only opening i know of is the door opening with a key where you can aggro tonberry on the other side ending with having mobs opening it without key)
