Kordeth said:Fallacious argument since swiping the painting would be a standard action--an action the non-looting character could be using to move farther into the next room.
Easily minimized if not outright eliminated by making the area of poisonous plants a little larger or repositioning it slightly.
Neither of these "proves" anything we don't all already know--1:1 diagonals are marginally less realistic than 1:2 diagonals. Nobody has ever argued anything differently--but both of these scenaqrios can easily be mitigated simply by the DM designing dungeons with the 4E movement rules in mind and adjusting differences accordingly.
I think you're drasticvally overestimating the effect of 1:1 diagonal movement, and that's speaking as someone who has many, many years experience playing variou editions of D&D using both 11 and 1:1 rules for diagonals. A typical character gets about 2 extra squares per move action--hardly game-breaking.
