farming vanilla content to get marks!/why?

[norak]

SOLUTION!

new inferno area
lots of Hard* mobs (drop nothing but mark but extremely low chance 1 in 100000) no normal loot bc its area for farming marks and such
no tele
end of area has boss with say 1/balanced chance to drop puzzle/mark whatever

basically an area just for the puzle/mark.

and by hard i mean HARD*

/i see future and say there is a new cruci-like area but for marks/puzles a keys being common drop and mark/puzzle being uncommon or even rare drop
