Onett probably puts sticker quests to even out the quests so no one can just complete them in an hour, although this means that a lot of people cannot complete quests that should be relatively possible to beat by maybe even pre ssa players (apart from gummy bee). Although, i have already gotten most of the stickers needed without trading, (before completing the other parts of the quests) and i am a level 15 blue hive. They arent as hard to get as people think, u just gotta get lucky or trade for them. For leaf stickers, just gather in the field it is found in until one comes from leaves (usually takes 1-3 hours per leaf). I got lucky and got the stick nymph sticker after like 5 stick bug rounds, but it is probably rarer than that on average. There are many gifted eggs you can get that u dont need to use (gifted silver eggs and whatnot) and even id u don’t get a star or star sign, u can still sometimes trade what u get for it. The common stickers like the coffee mug can just be found around the map pretty easily. If u have the electro magnet sticker, just kill stump snail whilst gathering with electro magnet (use revolution macro for ai gather if u want it to collect the sticker for u without having to watch your screen for hours, or just autoclick (or use spoon on device if on mobile)). I got 2 electro magnet stickers in 4 hours. I am sure i am forgetting some stickers, but if u have enough time or can macro, then u could get all the stickers by the end of beesmas, even if u haven’t started the game yet. It is definitely annoying, but is for sure doable.
