Blockers are already there, that's why those guys cannot hide themselves more than that. I don't think that's much of a problem, they're still easily catchable imo.
A player is supposed (I imagine) to be easily visible/targetable by their names being shown, when their names are being hidden through a (seeming) exploit in which you can hide your names, that seems to be an advantage bred out of system incapabilities at the time, not due to any logic that makes sense.
So I'm just wondering, is this something that will actually be worked on (eg: adding a wall making it impossible to hide your name) Or is this part of the fonline-AoP tactics that devs want to see being used?
In my personal opinion, it just seems to be an advantage bred out of an oversight. Not an advantage bred out of any logical "tactic".
