not sure if its just a coincidence, but i seem to have a difference in my spoiling power before and after. i might have missed something about the spoil skill, but my spoils would activate 100% on ALL mobs in FoTD and in Blazing Swamp, in the first try, before the big update.
but today i noticed that i had to spoil 2/3 times on the Hames Overlords and it still wouldn't succeed, and the mob would eventually end up dead before activating spoil. not as bad on the slayers/grinders but needed to spoil them atleast more than once.
Yah, its definitely a problem. I just came back to game and I have noticed that my spoil either doesnt activate or just doesnt stick. I manage to actually get a spoil around 1 out of every 5 or 6 mobs. :( Ive also noticed that the drop rate is a lot lower too, or maybe it just seems that way to me. I was used to getting atleast a rec or base mat from most mobs, but not now. that too is down to 1 out of every 5 or 6 at the least.
