the only "complaint" is the nature of the injuries and whether or not the types of injuries are REALISTIC, NOT frequency alone. REALISM is what we're all hoping for when we boot up this game otherwise we'd play FIFA or whatever, so lets get off the high horse and simply discuss what constitutes REALISM not possibilities or rng, shall we?
i've asked for data (in-game or IRL) and all i've seen is one gentleman suggest that the game has about 80% of real world injury rate. not much detail there though. still no answer on whether or not the scouting note "injury prone" means anything or not. or whether or not there are players "less prone" to injuries. these are all questions of REALISM.
we could start with current real world numbers...it's fairly simple to got to transfermarkt and browse the injury tables of the top 5 major European clubs, here's a link for Ligue 1 - https://www.transfermarkt.us/ligue-1/verletztespieler/wettbewerb/FR1
not a single broken leg, yet i see such injuries as "horse kiss". anyone ever had a player with "horse kiss"? it's obviously possible IRL.
yes, it's a snapshot of ONE season, but at least it's real world data.
so you're preaching to the choir if you're asking for realism, but let's not confuse possiblities with realism. unless you're trying to sell lottery tickets.
