Stick with it mate. First season I had a lot of bookings/red cards so I would remove hard tackling in-match when needed. Since then it's been fine. Notice u can get more injuries the more tired players are.. but again could just be down to luck.
Armageddon v3. No OI, no training, no match prep, tactic half fluid (competent). Just plugged it in n let it play as I was taking a break from my long term save.
Update/Works with lesser players.
Top tactic again TTF (H) (Won the lot with PureInsanity(v1) in FM14).
1st season was a write-off, finished 2nd miles behind Hearts lol! Down to me having zero reputation probably more than anything else...
Flying this season though (Media Prediction 8th)...
