In my experience after using TL for 2 wks, I've made more than 20M in credit and gained over 20k in free EXP.
Trick is to use ONLY lower tier premium light tanks or medium tanks.
German: T-15, Pz S35, T-25, Pz 4S,
USSR: M3 Light, LTP, Tetrarch, T-127, Matilda.
USA: Lucust, T2 LT, T1E6, Ram II, does not seem to work as well for some odd reason, maybe it gets pulled into higher tier battles or repair bill is higher than others.
British: Matilda BP
Vehicles mentioned above are likely to get better results than others using TL.
Higher tier (above 5,6), non-premium vehicles have higher repair bills, less profit & EXP generating probability.
I never use TL to play artillery..
Light tanks and faster moving tank gain more credit & EXP when TL just rush the tank out to spot 1/2 of enemy team, quick dead raise less suspicion to get reported as bot.
Matildas are less likely to be top of the starting list and slow moving tanks w/decent armor and fast loading gun actually get kills.
Premium heavy tanks like Pz B2, Churchill, Excelsior and T14.. but only when I monitor the progress of TL in battle, since they are more likely to be top tier tanks in random battles, using them will be more likely to get reported as Bot.
USSR TDs: SU-100Y and SU-122-44 are also decent credit earning vehicles, I also use TL with those TDs.. but to avoid getting reported as Bot, not as manay battles with TL.
I don't grind up German heavy line, so I do not use TL for the LOWE, JT 8.8 earns more credit then LOWE anyway, but credit earning and crew training potential for LOWE are there
Start TL before I go to bed and check 6-7 hours later, I gain few hundred thousand in credit, few hundred free EXP and my regular tank crew gain few % in training.. even without premium account, TL works great for me... until 8.11 kicked in, TL stopped working with WoT completely.
