Good morning community, I have a question i can't seem to find the answer to anywhere. I know some of you mathematics guru's might be able to help me or point me in the right direction. It has to do with increasing my wn8 to my current play level. I had approximately 7k battles 1000k wn8, after playing and actually learning the game and some of the mechanics i am now averaging 1900-2000 recent wn8 over the past 4k battles. My question is, is it worth going back to some of the lower tier tanks and increasing my overall wn8 in them? For instance I played 284 games in the T18 without a clue how to play, my overall wn8 is 644. If i go back and improve this overall wn8 will it directly correlate to my current stats and improve my overall wn8 or should i focus on the higher tier 10's to increase? At what threshold is it worthless and is it possible to dig myself out of a 7k battle deficit or am i just stuck moving up 2-4 points a night on my overall? Current wn8 1387 recent 2126.
