So as an ussr rank IV player, the IS and other tanks grind is very painful for me. And im gonna ask for a premium vehicle tip. . Warning: the premium vehicle price should not exceed the price of 60 euros and max tier is VI
In that case you have just single option and that is T-55AM-1
I would advise playing through the normal tree and spading vehicles, but if you’re going to buy a premium, I’d recommend the T-55AM1 for rank 6 or TO-55 for rank 5. Both of them are not top tier which is nice. I would recommend the TO-55 more because it is slightly lower tier meaning you’ll probably do better in it given that you are currently at rank 4. Both are really good though. The TO-55 is also cheaper. At rank 4, it’s slim pickings. Not many worthwhile premiums. My biggest recommendation would be the TO-55. The Rank 5 IS-6 is also nice, but I would still recommend the TO-55 before it.
One thing to note about the TO-55 is while it does have a flamethrower, that’s just a gimmick. It’s not useful in the vast majority of cases because it can only damage open-top vehicles. Just use the gun.
