In its current state [2018] its not good,
recently devs have continued to add vehicles to the game, and botch job fix some ballance issues, instead of properly fixing what is already in the game. its a real shame because WT has such potential, however its pulled back by idiotic design decisions on the developers part.

Pros: good visuals, wide variety of vehicles, reasonably good damage model design.

Cons: issues dont get fixed, unballanced gameplay, terrible communication to community, idiotic methods of 'balancing' vehicles almost pay to play at high BR, unrealistic in many ways, RNG based, extreamly expensive premium vehicles, bad 'net code' [almost always over 100ping], stupid flight model when damaged, moneygrab vehicles, refusal to use some valid sources for historical information [e.g hunnicutt], etc.

-moneygrab vehicles: when gaijin makes certain countries at some BRs difficult to makes players want to buy the new
powerful premium vehicle or buy premium time to win slightly more often and to reduce grind. [e.g. Ru251, XM1]
-unballanced gameplay example: M1 abrams vs Leo2a4, Leopard has better armour, gun, speed and a repair cost that is
6430sl cheaper than the M1. currently the leopard doesnt have a turret ring so its horrizontal cant be disabled.

gaijins process of adding and fitting in a vehicle:
1. add vehicle that looks cool.
2. german players complain its either underpowered or overpowered depending on if its theirs or not.
3. gaijin both changes the BR and changes stats of the vehicle, e.g. increased repair cost.
4. german players at the vehicles new BR complain again.
5. more changes to both BR and stats to make germans happy.
6. either its overpowered or too bad to play without getting depressed.
7. gaijin leaves it in a semi broken state.
8. gaijin adds another vehicle.
-results in vehicle having unrealistic stats, fighting the wrong era of targets or be unplayable
