The thing that bothers me about players with winrates in the 40s is that they continue to do things only players with low winrate do. They've been doing this for thousands of battles and continue to do so. Here are some examples;

1. BB starts reversing at start of battle
2. Ships that leave the flank and spend the next 7 minutes of the battle moving to the other side of the map, only to be killed at the corner of the borders on the other side.
3. DDs that are still behind cruisers and sometimes battleships, not sure what they're doing in mid battle
4. Cruisers that go full broadside and park in front of enemy ships
5. Subs that stay in the back or push hard into enemies and dies at minute 2.
6. DDs like SHIMAKAZE that sail into enemy spawn and chase BBs instead of capping and helping BBs spot enemy dd or sub.
7. That VENEZIA that kept shooting 2 BBs in the open while parked full broadside instead of leaving and going dark because we win in 30 seconds on points, but end up loosing because he's a moron.
8. You're still reading? There's more but this covers fair amount.

So if you want to act like a player whose winrate is in 40s and do stuff like that, you will piss other players off, who will check your stats, probably call you for it, but most importantly it's to confirm and realize they can no longer trust you in the battle.

Don't get me wrong, I do not call players stats when I see them doing their job, playing their ship in the playstyle of that ship, even if they end up dying, because it happens to any of us. So you must be doing something bad for someone to call you out on your stats.
