Thats 52 runs +/- in a week, with 3-4 boxes at the end. .which is 156 instances of a box being open minimum for one week, not to mention, been plugging at it since delves started and still not high enough for one single tinderbox? Seriously? So, 4 players, running weeks of delves seeing no Tinderboxes is acceptable as bad luck.
Then they supposedly they drop from mobs and treasure piles yet, my characters, nor my friends characters have any to report since go live?
So unless you have a invested interest in keeping the tinderboxes at 12k a pop per enchantment, or x8 needed for blacksmithing crafting, cause I have had no choice other than turn to the AH , I don’t like having no choice when i put in the effort to supply them myself. It’s a bad system. period.
