Worst tank for each br (imo)

All these are my opinion based on effectivness on its intended role and an explanation.

BR 1.0 FCM 36. Horrendus at everything, mobility horrible apcr, except good armour at an extent. BR 1.3 Ro-Go: Bad armour, horrid mobility andgun(s) really hard to aim and do no damage. BR 1.7 Pvlvv FM/42: Honestly not bad but most 1.7 brs are quiet good. Comparable to Ta-Se but this has no armour, 2 crewed and mid armament. BR 2.0 M13/40(II): Again not the worst for BR but still pretty bad. Mid mobility quiet bad gun for BR and quiet bad armour. BR 2.3 PBV 301: Horrible gun for ground but alright for air. Napkin armour and ok mobility. BR 2.7 BM-13N: Impossible to aim, no armour, ok mobility, good firepower but you won't hit anything. BR 3.0 So-Ki: Bad mobility, horrible guns for killing ground targets and ok for air, napkin armour. BR 3.3 YaG-10 (29-K): Horrible mobility for a truck, no armour, cant engage targets unless in front of you. BR 3.7 90/53 M41M: This vehicle is ok for BR but most 3.7 vehicles are quiet good. Has excellent firepower but that's it. Has mid mobility, no armour and horrible gun handling. BR 4.0 BM-31-12: same as Bm-13n BR 4.3 TCM-20: 4.3 doesnt have bad vehicles but this vehicle is lacking in firepower and armour. Mobility is quiet good. BR 4.7 SU-100Y: This vehicle is massive, has horrible armour and quiet slow. The gun reload also dampers on it. BR 5.0 ZSD63/PG87: Not a bad vehicle but just slow, horrible reload and can be 50 caled. BR 5.3 U-SH 204 GK: Cant pen anything except light tanks, can be 7.62 from the side but excellent mobility. BR 5.7 Waffentrager: Can't bear with that mobility and armour. Way better 5.7 td for Germany. BR 6.0 R3 T20 FA-HS: same as USH BR 6.3 ZSL-92: Can be 50caled, not even mobile and bad gun. BR 6.7 Type 60 atm: missiles go straight up so impossible to aim, bad armour and ok mobility. BR 7.0 Type 75 MLRS: Hard to aim missiles, bad armour and ok mobility. BR 7.3 AMX-10M: Hard to aim missiles, bad armour and om mobility. BR 7.7 Type 87 RCV(p): Basically a Wiesel that is quiet large and higher br. BR 8.0 M41D: Horrible dart, basically does no damage, no stabiliser and bad mobility. BR 8.3 Giraf and M11a3 (Tow) Fun but getting kills is hard. Missile travels slow so people can just dodge them. They also only work in long range maps. BR 8.7 CM25: Same reason as Giraf. BR 9.0 M60A3 TTS (Taiwanese): Horrible dart, sub 300mm pen, horrible mobility for BR and no armour as it's an M60 at this BR. BR 9.3 Type 93: sorry for enjoyers of this vehicle. Has less missiles comparable 9.3 vehicles no armour literally and mobility doesn't matter because people can just mg you. BR 9.7 Ozelot: same reasons as type 93 but is honestly good at aa. BR 10.0 LOSAT: Really hard to aim missiles that work only in far range and is impossible to get a kill with in basically any cqc. BR 10.3 Antelope: Same reasons as type 93 except less missiles. BR 10.7 Freccia: This vehicle is not bad in any means, it just has useless spikes and a gun that is comparable to those in 9.3. BR 11.0 Tor M1: Not a bad anti air just worse than other 11.0 equavilants. Has no secondary gun to protect itself, smoky motor so aircrafts can see you fire. BR 11.3 HQ-17: Same reasons as Tor-M1 except higher BR. BR 11.7 Challenger 2 TES/OES: Honestly not bad but not good. It has bad mobility for BR, protection doesn't matter as challenger 2 has pretty obvious weakspots. Gun is ok though. BR 12.0 Leclerc Azur: Mobility is worse than other leclercs, armour is paper for BR and gun is good but not the best.
