USARABAT, thanks for your suggestions but on the future please focus more on one of them by time rather then 10 in the same topic as is hard to discuss about all of them and do follow all of them. Rather let's focus on one per thread so we can develop the idea more in details.

Anyway, here is my opinion:

Training stops at level 91 - finished it more than seasons ago .... maybe level up the world class drills to super star level / legendary level drills ....
-More or less you are right. For those who already reached the highest level is quite boring at the moment. I did it very long time ago, maybe a year ago so imagine ... yet is hard to go there endlessly. If you follow different games and so on you will see that some stuff eventually will get to the end. Sadly will be like for us too.
More then sure at some point they will give some extra ones but very likely to see 20,30 more, maybe 1,2 from time to time, who knows...

Red packs ; I've over than 1500 red packs .... I suggest allowing managers to exchange them for rests - morals - tokens ...
-Actually it has been suggested lots of time in the past and I don't think is an impossible idea, I do believe we will have it at some point but expect to be on a rate that will be in the game advantage. I saw lots of games with this kind of stuff but all of them have the same thing, rate 2:1 in favor of the game so would be like you give 10 red boosters and get back 5 green ones. Changing them on a rate of 1:1 would be impossible!

Academy : boring ... i sign the 2 stars players and sell him in next few hours - the other one needs a lot of training ... also not useful ...
-True is boring but I don't think you can do to much regarding this ... like to create something WOW out of it.

Achievements ( club history ) it's secret no body can see it unless I make a screen shot and go post it on fb or here ...
Auction: makes you waste a lot of time ( already suggested to increase the number of players from 15 to 30 players per round with all positions each round )
-This goes along with Trophy Room and so on, sadly can't be seen by others managers indeed. At least they can make the trophy room visible as it was before, would be good enough!

Club
- I think is good enough, some small improvements can be done but nothing much and to be honest I do not really agree with expanding the games way to much, will require to much time from players.

Club Shop
-There are lots of things to be done with but at the moment looks like a big mess for me Hopefully a redesign on the page would come out someday ...
