Newcomer questions about crew training

Doc_Skinner, on Sep 29 2014 - 14:36, said: As you can see from my stats, I am a real newcomer to this game. I have fewer than 500 battles and my win percentage is pretty low. But I have read everything I can get my hands on (something to do at work when I can't play) and think I have a solid plan for advancing through the game tiers. I've heard arguments for racing past tiers I-IV as well as arguments towards staying at I-III until you get a solid grasp of the game and good crews.   Currently I have M3 Stuart (Elite), M2 Medium (Elite), T18 (Elite), M7 Priest, Vickers Med Mk III (Elite), PzKpfw III, Marder II, Wespe, and T-26   My problem is, I just don't see how I can get my crews to 100% in any reasonable amount of time. I have elited about half of my tanks, and even with the double experience weekend we just had they only went up about 4%. I am itching to purchase some Tier IV tanks, and I can pay credits to start them at 75%, but then I am right back where I was in my Tier IIIs -- creeping slowly up from 75%.   I probably won't be keeping any of my lower tier tanks when I upgrade, so I can keep some of the crews and retrain. I know I screwed up somewhere and wasted the 100% experience in the Tier I crews when I didn't understand the training system -- some of my crews have skills partially trained even though they are now below 100% experience.   So how reasonable is it to get crews from 75 to 100% so I can start getting some of the skills and perks? I do plan to buy some premium when I know I am going to have some time to play. Should I just bite the bullet and buy gold to train crews to 100% when I get my Tier IVs (or maybe Vs)?
