Hey, hi went there to check that spot since was some of my Aliance members (LUSA) in there, they were on TS3 with me all the time and was me who ask to move golems to that gate.
They jump to that ledge to run away from enemy fire and jump to water, few mins later i went there to check if theres any exploit in there and i take few screen shots and send to arena.net already in 1 ticket, i wasnt able to test it right since i was in combat mod all the time, but 1 necro fear me and i went to next ledge, ive see alot Desolation members trying to jump to inside fort and no one was able too, all fail, so idk if its even possible.
But again, hisent ticket to arena already with the SS´s reporting that and ask to check if its even possible jump to inside from there
