Mini games are ok. I personally disagree with them being associated with crafting. I think crafting should be meaningful, hard and time consuming. However, I come from an age of grinding so my vision might be skewed.
I think that it all depends on how influential crafting is going to be. I read on the blogs that they want it to be a player-created/item centered game..so I think mini games don't need to be there. Just don't make the click/chop take 9 hours. One aspect I've seen is skill = clusters. So a person with 1 Mining skill gets 1 ore per hit, but by the time he's level 20 in mining he gets clusters of the ore. Granted this could have economical repros, but that is a whole different discussion.
