Is the magic wall "log out jump" considered a game weakness exploit?

Question

At least for Retro PvP and Retro Hardcore PvP, things may work this way nowadays: Player A is fleeing from Players B, C, D and E (but Player B isn't with PZ locked status, because he was not attacked so far) in a certain dungeon. Player A finds a narrow passage (long corridor with 1 SQM of width, so only one player can pass each time), and he casts a single Magic Wall there.

Apparently, Player A is saved as long the magic wall is on (or as long as he has more Magic Wall runes with him). But that's what happens with Player B (the one without PZ lock): Player B can log out right in front of the Magic Wall, Player C goes to the place of Player B, and Player D moves right behind to Player C and Player E goes right behind of Player D. Once Player B logs in again, he will be at the other side of the Magic Wall, and now Player A will be troubled even though the game mechanics weren't designed to work this way...

The question is: Is the Magic Wall Jump even legal? Is that a game weakness exploitation? This whole case is actually a by-product related to the change that made "Depot/Sheep Teleport" impossible to happen... So it is very close to a bug or game weakness exploit in my opinion...

Answer 1

For me its looks like 100% exploit and should be fixed, because unlike tp exploit it is much more harmful.

I agree. It is a problem in my opinion...

Answer 2

In my opinion it is as it has to be. This is the only way that you have in retro pvp server to jump into a trap. Moreover, this is the same technique used to move enemies away from their 'sios' or the ones that are 'potting' them, how? If I got an enemy close to me, and it is necessary to push him on my sqm, and every sqm in the area is take, I would log out, he will be pushed into my sqm, and a mw will me throw to the sqm he leaves, so when I log in again I will appear standing in the mw where he used to me.
Deleting this in open pvp was fine, because there are other tricks to push people or to open a trap as 'stacking' mw so you can make the enemies think that the mw that they see blue are theirs and not yours. This way one a member of your guild see your mw yellow he will be able to enter the trap.
