2 years is a little overexaggerating. here were the drops just from 2014 (i agree with you even in this season tho, it was half the drops of other shards)
Taryns Book Of Travels (10)
The Shirt Off Of An Unlucky Leprechauns Back (~40)
I Found Farmer's Brown's Prized Pig (10)
A Strange Flask Swirling With Dark Power (Caution: It Looks Volatile) (10)
EM Faine Morgans Enchanted Cook Pot [Caution STRONGLY Advised!!!] (~30)
Grinch In A Gift Box (20)
I felt EM Faine Morgan was one of the best storytellers in the game, with good drops to go along with excellent plotline. Its a shame she did not have the rl time for it anymore.
I dont know the name of the short lived EM who only did 1 event (Grinch in a gift box holiday drop)
I understand your frustration tho, were almost 5 months into 2015 with only 1 drop so far - Mar 17 - Luckys Pot O Gold (10)
Hopefully once the new EM figures out his or her bearings you will see drops again. Its also unfortunate Origin had periods of no EM, and also long abscences from Faine Morgan before she decided to retire from EMing.
Personally, what i like in events is a solid, engaging storyline that has some depth but at the same time isnt impossible to follow, with reward items that tie in well to the story.
