A short answer and our recommendation. You may have a different opinion (and that’s perfectly fine).
Tier X (free lines):
• 🇯🇵Type 5 Heavy (HT-X) [main OP 2.0, but this gameplay isn’t for everyone]
• 🇬🇧FV230 Canopener (HT-X) [requires some skill, leads to Tier XI]
• 🇺🇸T110E5 (HT-X) [leads to Tier XI]
• 🇺🇸M48A5 Patton (MT-X) [leads to Tier XI]
• 🇨🇳BZ-75 (HT-X) [leads to Tier XI]
• 🇫🇷Bat.-Châtillon 25 t (MT-X) [leads to Tier XI, but it’s weak]
• 🇬🇧FV217 Badger (TD-X) [leads to Tier XI]
• 🇨🇳WZ-113G FT (TD-X) [not suitable for everyone]
• 🇯🇵Ho-Ri 3 (TD-X)
If you’re a complete beginner in the game, your Tier X choices should be: 🇯🇵Type 5 Heavy and 🇫🇷Bat.-Châtillon 25 t.
Tier XI:
• 🇺🇸T-803 (HT-XI) [as expected, the main OP of Tier XI]
• 🇺🇸XM69 Hacker (MT-XI)
• KR-1 (HT-XI) [requires understanding the tank]
• 🇨🇳BZ-79 (HT-XI)

No IS-7/KR-1 line for newbies as suggestion?
Guess OP had his fill of Steves.
I picked the line I had least research done. I play tanks until I get ace tanker on it then I move up the tree.
Chems made a perfect tier list video that compares the tier 11s relatively tier for tier to the tier 10 tanks, go watch.
Nobody watches that pedo
Skill, is that you?
Picked Chinese light line and oh oh oh…T10 is sooolid after buffff
Solid for doing dmg and running after you get spotted. But it still pales in comparison to Manticore, T-100LT, EBR and AMX 13 105 in terms of spotting. Until WG introduce the “Damage-dealing LT” and “Reconnaissance LT” subclasses and match the lights accordingly, LTs, such as WZ-132-1, Sheridan and Tesak will never be competitive.
Suggesting Batchat line for beginners… how drunk you have to be, to imagines something so wild? 😛
Beginners should go to some armored heavies or sniper TD’s, not paper autoloaders, which require some skill to be played.
You speak like you would ever had a single skill 😀
Everyone knows that you should pick your ride depending on how sexy it is….and colour!!
