4 year player, not many have the perspective I have. Wargaming makes great games, but they're immoral.
Ships that I have personally seen bait and switched about to be listed. Bait and switch = sell something to people, knowing full well that you'll have to nerf it, which you then do shortly after the sales period.
Tier VIII Kidd: Had AA significantly nerfed, which matters as the selling point for this boat was AA.
Tier VII Atlanta: Had AA significantly nerfed, which matters as the selling point for this boat was AA.
Kutuzov: Had smoke mechanic reworked, removing its ability to stealth fire from smoke, a key selling point.
Kaga: CV gameplay was completely reworked, making the ships in practice entirely different than they were marketed as.
Saipan: CV gameplay was completely reworked, making the ships in practice entirely different than they were marketed as.
Blys: Guns were significantly nerfed, which matters as its guns were its selling point.
Sims: Had guns and AA significantly nerfed.
Belfast: Same smoke mechanic rework that nerfed Kutuzov also nerfed Belfast.
Those are just the ships I personally have experience with. Do NOT give this company your money. You're not going to get what you paid for. Ever.
