Yes, that are the disadvantages. That are the risks of the transfer market. First, the right players must be listed (something that I had trouble with last year, and I had to make use of the scouts list), you must be there when they are listed, and you have to win the bids. The scouts and recommendation lists might be more convenient, but there is also the negociations' list.
If it was during the period when I was here last year, maybe I would have bought some of those recommended players. Such players, albeit tempting, don't fit in my plans now, as so far, from what I have seen, the ratio benefit:cost is poor when considering that you can achieve more or less the same in terms of winning competitions with cheaper alternatives (when I mean cheap, this means no power training included as this option turned out to be even more expensive). If 'free' earn-token offers were available in my region and I was able to earn enough tokens, may be I would have added a few recommendation players to my team. In my opinion, this new feature will provide something extra for users who intend or have to use the scouts' list.
Of course, for those users who have been generally satisfied with recommended players and can afford using a lot tokens per player, they may do so until they are no longer satisfied, can no longer afford them or no longer feel the need for them.
