You know, I'm increasingly tempted to add the Wotan to this list.
I really want to like it, but it always seems to underperform every time I field it.
It's main gun is just really underwhelming for the points, especially since it only has a crappy MG44 as it's secondary weapon.
The release of the Laser Jagdgrenadiere was really the last nail in the coffin for the Wotan, I think, since you can field two of them while spending two fewer points.
You would think that the extra armor and health on the Wotan would make it more impressive, but it doesn't really seem significantly more survivable than a Ludwig. Two bazooka shots will drop both of them just as easily, and it's quite embarassing when your 58 point walker gets blown up in a single round by a lowly 22 point Bot Hunter unit.
