I've found to great annoyance that decrypting exotics or opening CoE packages while at 335 ll gives 334 items more than half of the time. But, opening at 334 ll has always given me a 335 item. I believe its still possible to get 334, but so far its 100% worked for me to drop ll to 334 when decrypting. Edit: see below, I have since got a 334 item, but still working better than decrypting at 335.
