A good idea to have a feedback thread, but it would have been more informative if you had listed the last dozen or so events and asked for a good/indifferent/bad rating.
I'm not fussed whether it's harvesting or crafting, it can be enjoyable or not, depending on how well it is thought out. Also for me completing the quest is the important thing, regardless of whether the "prize" is useful or not. Fortunately I still have enough room for almost everything I "win".
I have a few suggested dos and donts for the team, some of which may have been mentioned already.
DO
Have more untimed main story line events.
Have community visits and heart collections, not just neighbours all the time.
Reissue some of the older events which newer players have missed. I was very pleased with the summer gazebo and glimmerbat for example.
Learn from past mistakes.
Keep players informed at all times.
DON'T
Alienate Android users by having IOS only updates.
Make timed events dependent on random drops.
Move the goalposts during an event either to make it harder or easier.
Release ANYTHING without being sure it works properly.
React to criticism with a knee jerk extra reward.
