It is a shame that, again, the rogue rune quest involving “C” (Deadly Brew/Shadowstep) ends with a tedious run through Silverpine, back to a major city, and then back to SFK again. If you’re alliance, you need to hearth and then fly back to Southshore and then run back to SFK.
The entire “you get the letter mailed to you when you enter a city” feels incredibly gamey and contrived. Also, why is the dead-drop site still SFK? I thought that was a matter of convenience considering the last mission was SFK focused. Are there not enough rotting buildings near SM to do a more convenient dead-drop?
Next phase, it would feel both much more convenient and appropriate if, by now, us “repeat customers” can be trusted to just return the item and loot the phase 3 rune at the (hopefully new) dead-drop site simultaneously. There’s no mystery anymore in how these letters work. The lore flavor letter we get afterwards, on a now random timer, will probably feel a lot better too, rather than an incredible inconvenience.
