So for anyone who finds it impossible to get through more than 3/4 seasons (most of my saves end up that way)... i've managed to somehow find some enjoyment even into season 7. Here's some findings...
Playing as Palace for the first 3 seasons i was sacked towards the end of season 4... ended up at League 1 Southend who for some reason had a yearly transfer budget of 38mill with a wage budget of 58k (which equalled out to about 32mill at 100k wage). Really low board objectives except for finances (which makes a nice change, at Palace the objectives were getting ridiculously unreasonable).
So i spent 2 seasons just simming games.... the initial squad was rubbish (mainly mid/high 60's overall players all of which were 24+ years old)... following the realistic transfer system i ran at Palace i just went with whatever i wanted at Southend... irrelevant of overall or clubs the players were at, if i could afford it i would sign it.
So i firstly signed up all the decent free agent youths (at the start of season 5 there were some excellent 18/19/20 year old free agents... many who were 70+ overall with a few being 76+). I also bought up an 81 ovr striker for something like 25mill and pretty much blitzed season 5, finishing 2nd and being promoted... using the training sessions on the youngsters, i ended up by the end of that season with a squad of mostly 75 or better overall starting XI players.
But i digress, this isn't about the squad i had....
By the start of season 6, regens are rife.... Messi's regen (who i noticed was retiring right towards the end of season 5...) suddenly appeared.... at Stuttgart... which i didn't realise was possible.. i thought all regens re-appeared in the country they retired in. This however does seem to be an anomaly as what i expect are nearly all the other regens on the game have re-appeared at clubs in the country they retired in.
By season 6 you also get alot of auto-generated youth players at clubs... but this is where the issues start to appear. Regens generally have good work-rates (Ibrahimovic's for some reason was low/low however his regen was still 83 ovr by the time he was 23), but the youth players are really crappy... my shortlist must contain a good 50, 19 or younger, year olds. But i'd say a good 40 of them are low/medium or medium/low work-rates. Exactly zero of them are high/high and maybe 3 are high/low or low/high, and i've come across maybe 10/15 in total that are medium/medium... equally through about 70 scouted players 21 and younger i've seen about 5 players with a trait, and i think 3 of those were 'injury prone'... not seen 1 with 'flair', which is as big an issue with regens too, pretty much zero of them have traits too, the Messi/Lewandowski/Buffon/Thiago Silva/Ibrahimovic not 1 trait between them.
The game also starts to become really unbalanced. My Southend team are in the Championship and in season 6 (having had a look through the import tactics screens at other clubs in the championship) some teams are really overpowered, Reading who don't seem to do much at all have 5 players who are 83+ overall in their squad, Brentford have 4, 82+ players and West Brom who keep getting relegated and promoted have 2 who are 88+ and in total 8 of their starting XI are 80+. While in the Premier Huddersfield have only 2 players over 78 ovr!
There's also a bug from older FIFA's that i thought had been squashed but has reared it's head again, and that's club's who don't have a goalkeeper.... Hull played out the entire season 6 without a keeper, finished rock bottom with only 11pts in total and a goal difference of -104... start of season 7 and they still have no keeper! Which is ridiculous...
The final point to make is the free-gen youths... they make a mockery of the youth academy... when you (unless you start training them up before promoting them) can at best promote a youth academy player at maybe 65 overall at 18... these guys are on the free agents list at 74 overall+ with far superior physicals and (sometimes) excellent work-rates by comparison.... it's all very inconsistent and annoying.
