Q&A.
You are somewhere low middle in the pack of players as a whole, but improving = good.
Correct. Don't play high tiers till you are more proficient. The higher you go, the more small mistakes can get penalized.
Correct. It can be hard to get into battles due to 5.5, tech tree gutting, ... so if tier 3 & 4 are not viable, tier 5 & 6 may be where it is at. 100 battles. That used to be the metric for ranking in wotbstars. It does not apply to anything currently, that I am aware of. If you play 1 battle, it will show up.
Focus. Play more battles in less tanks. Overal one can become a far better and more versatile player, by playing all tank types in all nations ... but that takes a fair bit of flexibility and adaptation, to do. For a while, while moving up the tiers slowly, with a relatively small garage, I used to play every tank I owned for the 2x win bonus. Or all the grind tanks for all the 2x bonuses.
Here's what I would recommend:
stop worrying about the 100 battle thing
pauze high tier play
pauze tanks with low wr
Old rule of thumb:
when grinding, get the tank to 50% at least and then move up
only move to the next tier when you have 50% for that tier
So, what we are seeing, as is common, lots of tanks getting played and grinded through, and lots of high tier premium purchases, while not quite understanding ins and outs of how to play better, ...
You have 7000 battles and played 176 tanks, so you have spread yourself thin. ( in comparison that's about the same number of vehicles I have played )
TDs. 50% WR almost 1% damage ratio, 23% survival
I'd park the TDs. Easy to camp in, easy to do ineffective damage but harder to win in. Lots of vehicles without turrets. I don't think it's good idea to focus on them because it is harder to be effective in them, and if the goal is to move numbers up, be better overall, I'd start with heavies & mediums.
Heavies. 48% wr 0.7 damage 25% survival.
You should be better at playing these first, get damage up, learn to hold cover, hull down, sidescrape, 25% survival is simply not good.
Mediums. 46% wr 0.7 damage 22% survival.
As above. Damage needs to go up. Learn to peekaboom.
Lights. 43% wr 0.6 damage 20% survial
Don't play lights till you are better at mediums. As above. You yolo, over expose, do hardly any damage ... difficult play style, harder to win in, guns are weaker, no armor. Do heavies and mediums first.
I would recommend tier 5 6 7. Plain old standard battles, to take the supremacy part out of the equation.
Do some tank(er) rehab. Maybe warm up with a couple games in a good medium or heavy in tier 5. Then go to project tank.
Some tanks, that to me are key to do well in, for further enjoyment and growth are the: M4 Sherman, T-34, KV-1, T1 Heavy.
If one can make those work, plays as smart as possible, deploying every tactic to stay alive, dishing out damage while minimizing incoming damage, one should have a damage ratio of 2 and 40-50% survival.
Key concepts:
Don't YOLO. Don't be that guy rushing out to his own death.
Hard cover. Use hard obstacles and terrain for protection.
Hard cover to hard cover.
Don't overexpose. Expose only as much as needed to spot, take the next shot.
Don't do bad trades, where you fire one shot but eat three shells.
Slice the pie. Only expose to one red at a time and work your way in from the outside of your viewing field.
Setup for success: make sure you have multi repair, adrenaline, single repair ... so you can repair tracks and get out of dodge, so you can extinguish a fire instead of burning to a crisp ...
Make sure you have some premium ammo - click the gold icon to switch to silver - and have 6 - 12 premium shells on board, so that if need be, you can use a prammo round to damage an enemy or kill them.
Don't be a hard headed solo guy, go with the flow. There is strength in numbers and stubbornly going the " right " way only to find yourself in a 1 v 3 and dead 60secs later ... does not help you win.
Learn to peekaboom and bait enemy shells.
Learn to hull down.
Learn to sidescrape.
Sometimes the best shot is not the one in front of you, but a sneaky shot into a weak enemy in the middle of the map, that takes a red gun out and keeps a green alive.
Keep an eye on the minimap, while in hard cover and reloading ... where are the greens, where are the reds, why are you only seeing 3 reds ... where are the other 4 ? deep flanking? ...
After you die in battle, think if there is something you could have done better, stick around and see how the rest of the team does ... watch how the other players play ... observe their good moves, learn from their mistakes, ...
Watch some videos on a tank before you roll out. Of course mastery games with monster numbers can be very hard to repeat, as they may depend on a weak enemy team and some lucky bounces.
And there's always more to learn, practice, but ... you have to primarily focus on hard cover, doing more damage, staying alive longer. Learn something from every battle. And keep trying to do better.
Good luck.
