Yeah I don't welcome the idea of running the BL-9 in tier9 but what can I do :/ At least it won't be as bad as running the T29's 105mm on the T34, LOL. Did you get the IS-4 turret+gun without the tracks? If so, which piece of equipment did you swap out for the doodad that lets you carry more weight? vents?
I don't remember exactly what I did to make the IS-4, got it such a long time ago. I do see an improved suspension in my inventory so maybe I used that and then demounted it after I got the tracks. Still, you can do the math to see if the turret + S-70 throws your weight over. But the thing is heavily armored anyways, and BL-9 still hurts plenty on a flanking shot. Just don't trade shots with a decked out E-75, 4502P or whatever.
I also didn't get any modules on it until there was a sale, so maybe there's enough weight allowence there... :awe:
I do remember for the E-75 you had to get the tracks to use the 2nd turret because its like 4 tons heavier. So it'd be tracks -> turret at the very least. Without the engine and the top gun you're a more sluggish but heavily armored KT. I got the gun before the engine but man, this thing is a SLUG without the top engine. I played like 3 games with the 128 before free-exping the engine.
I can tell you that without the top engine, once you start in 1 direction you won't be able to change your mind. It's like a KV-3.
Also got my master tanker reward finally, turns out I was missing an IS-7 in my list. (!?!?)
