Using Egg trap when you not under Progeny's blessing now interrupt using other skills right after it for like 3/4 second (in other words - triggering global cooldown).. and overall mechanic of that buff seems sick due to combined factors of 3 sec egg trap duration, you need to actually hit birds that hatch (and they're also freaking slooooooooooooooooowly expanding) from it and incredibly small duration of buff. Solutions to make it somehow worth even wasting points is (from best to worst in my opinion):
Remove needing of being hit by birds, just make it apply after egg explode no matter where or just make them expand at lot faster speed so you won't need to stand still waiting till they hit you;
Make egg traps explode instantly (in other words, change to spike nova);
Extend duration to at least double of it's current value so you won't be forced to... again, stand still for 3 seconds each 5-6 seconds of actual play
