Per your last 4 replays:
Game 1 on Westfield - your initial deployment position is too far forward - no tank should be in that forward hill from your spawn. If they had anything with a hulldown cresting their top hill, you would've been dead much much sooner. You basically drove yourself right into a crossfire from the get-go. That's why you lost so much hp - and then finally when you were down to a 1 shot, you went to a position that this tank will struggle to play - the far side crest. Because this tank has depression problems, you can't work that spot (usually).
I have a replay, same side of the map on Westfield, but an all tier X match that I can share with you, if you want to see what I would have done. Just PM me if you want me to send it to you.
Game 2 (is the same game as the previous - check if you pasted the wrong link)
Game 3 on Ruiberg - for your initial position (where you crossed over and worked from F2), generally that is fine, but it requires you to have enough support (mainly from G1). As you were driving/deciding to commit to that pocket, at 14:40-14:35, you need to recognize you didn't have enough heading to G1. Instead, I would've played G1 from the outset in this situation.
Again, I have a replay of that same side, though it is encounter mode and all tier X.
Near the end, you took unnecessary damage from the VK 100 P and AT 15. You could have just used the wreckage next to you to dispatch the VK 100P for free (without taking any damage). Also you blew a shot as you approached him. Then on the AT 15, you took way too long. At that point u need to be rolling (they are on cap circle and you are down in tanks), but you hesitated, tried to sidescrape, still took damage from the AT 15 and you were toast.
Game 4 on Prohk
Right off the bat, you can tell arty is aiming around F5-F6, one of the most predictable places. After he slammed the Leo, that should tell you, you need to shift and relocate every now and then (if you plan to stay there). Way too often, I saw you tunneled and sitting in place at F6, when the arty has already announced he is focused there. At 13:50, after you had just shot the Lorraine, you should know to be shifting position (as the arties are about to finish reloading). Instead you move to EXACTLY where the Leo JUST WAS AND GOT SHOT. Like c'mon dude. You deserved to be hit for being so damn predictable there.
From, 13:40-12:30 you should have used an HE shell to knock down that F7 straw hut house that is blocking your F5-6 angle shots to the east hill. Instead you're too focused on spotting E6, which I don't know why. The enemy bat just threw himself away like a moron. Your own light tank (RU 251) is actively scouting and super healthy. This is 3-5-7 and you have a huge advantage.
Instead, you keep sitting in the most predictable place, and you take your 2nd arty hit.
While you guys did hold on their initial (dumb) 1-2 line push. Had you been on the 3-4 line, which I would have preferred, you guys could have done something right away to punish them and completely wrap them. Look, they just threw away their Bat, 268v4 and a type 4. You should know the Jagdtiger is in middle, so is the 5a. That leaves very little resistance and you could've easily countered (had you stayed healthier) and just zipped up the match right there.
Instead, you sat at F6 ALL GAME.
Also if you don't choose to win/finish them via 1-2 line, then you should have driven up the 6-7 line (much earlier). Then when you did cross the tracks (for the 6-7 line), you tunneled too hard (timer ~ 6:20) on an already dead tank - the Standard B, while never focusing on the last super big threat to your team - the 5a. And you took two complete side shots for free while not paying attention. Don't bitch about being double ammo racked. That was your own tunneling mistake.
When he shot you the first time, all you had to do was rotate your body onto the hut that was protecting you from him. Then all your hill teammates could impose their guns on him. Instead you drove forward to expose your ass for free for that 2nd shot. Why are you tunneling against arty, 1-shot unarmored tanks? You are in a 3-5-7 match and need to respect and properly maintain your attention on legitimate threats.
Your RU 251 was alive all the way to the end of the match and was actually somewhat competent. I'm sorry to say, but this loss was on you.
