Not when you can spawn twice in a T-34 1941, 1942 or STZ for the price of 1 KV-1E. I would imagine people will prefer 2 T-34-76s over 1 KV-1, 2 T-34-85s over 1 IS-2 (1944) or 2 Panthers over 1 Tiger II. Even 2 Panzer IV Hs can be better than 1 Tiger I, if all you fight are T-34s anyway.
Especially when that choice only appears on the second spawn, because a heavy tank would be too expensive to spawn in at the start. On the second spawn bad mobility is a pretty big disadvantage, when everyone is already on their positions.
- It’s your job to position yourself in a way that will allow you to kill him, you are the one with mobility advantage.
- You don’t even need to flank him, just face him straight from the front.
- If the turret is angled he can’t hurt you.
- He can’t angle to everyone at once.
KV-1E/B is strong even from the side, but it’s not difficult to pen, you just can’t pen the side everywhere.
The side is so strong mainly because players are surprised, that they can’t pen a flat side. I got surprised too, but guess what, it only works the first time. KV-1E/B is just a rare tank to see.
Besides, tank destroyers exist. They are very cheap to spawn and are a very effective counter.
What would happen is that not many people would play heavy tanks, because tank destroyers, that are already waiting on their positions, can easily counter them. Not many people would play tank destroyers, because they know, that heavy tank players know, that they can counter them.
If heavy tank population increases, so does the tank destroyer population, like in nature.
Everyone would play mediums tanks, because they are stronger than light tanks and don’t cost much more, and they are more flexible than tank destroyers.
