If you look at the required specs ( and meet them) to be able to play RO you will not need the 5 second delay once you have warped into a map, to stop the "Abuse" and "Lack of consideration" on our part we are making the immunity 1.5 seconds thats a full second more, note we will not increase it by more, if your computer specs do not meet the ones required by Gravity use your common sense, and warp a few steps away from your destination. This will be implemented tomorrow along with other updates.
PS: Devil, they did not do it to protect themselves solely, they also did it to attack you while warping.
