Generally speaking run out of the marker and jump, except for the final phase of Titan HM - well, actually, still do this if you can, but beware jumping off the platform accidentally... The jump forces an immediate position check, otherwise you're at the mercy of the polling interval on position checks, and the telegraphs use the position the server has for you at the moment they end, so you could have moved out of the area and there is still a small margin of time where the server believes you to be in the AoE because of the 'old' position check. If the next check doesn't happen before the AoE is processed, you're gonna get hit. But if you jump as soon as you exit the marker, you force an instant position check without using a GCD or oGCD ability.
