Now, the sturmtiger is already a pretty sick unit if you know how to use it. I don't feel it's a good idea to have it vet up fast.
This is pretty much the thing with a LOT of OKW units.
They start off as really good units, and by vet 3 they're serious powerhouses. Vet 5 heavy units can, and often will, single handedly break the game you're currently playing with a sickening crunch.
Take the vet 5 command panther again. Even at vet 3, that thing is amazing on its own (a panther that spots for itself and has mark target) and makes your other and allied tanks great.
At vet 5, you have a unit so amazingly good that entire armies quake at the mention of it. That sort of thing straight up should not be showing up in the majority of games (unless troop training abuse because seriously that's silly).
That's the sort of unit that you only should be seeing at the end of long, bitter stalemates. It's the sort of thing that ends an hour and a half bitter grind. And I HAVE got one to vet 5 without ever needing troop training to be on it. My ally was elite troops but that panther never went into my base sector. It was too busy fighting off endless swarms of Easy 8's and T-34-85 on crossing in the woods. That single unit, once it was fully vetted up, is a good chunk of the reason we won that game, and a long one it had been.
Similarly, I've seen a vet 5 sturmtiger. The passives are all just sort of okay, but once you have one you have a reloading machine that can point, shoot and wipe all day long. It breaks games. And the only time I feel the game should be broken is if it needs breaking to end a stalemate.
I appreciate that it can be saddening, especially in 1v1, to never see those 5 start over a unit. But just ask yourself a question, with most of them; do I really
need 5 stars to kick ass with it?
