As we all know, many players jokingly refer to the Mystic Forge as the “Mystic Toilet” due to the fact that it often feels like you’re “flushing out” items when trying to, for example, acquire a precursor.
My idea: For next April Fools day, have the forge literally transform into a huge toilet (just like it changes appearance during Halloween/Wintersday)! It might be a bit weird, but I feel most players will get the joke (or be told by their guildies).
Additionally, have the forge make a “flushing sound” every time you use it. Would be quite hilarious, I imagine.
