The Tiger is a very easy tank to get carried away (Not in a very bad way...) ordering upgrades one after the other, there are just so many parts available. In my experience the idler mounts are the main weak point so for now mind your terrain and keep the turns gradual over grass.
Weight kills the Tiger, but tracks aren't as bad as they seem.. they're already sitting on the ground
When we have our first meets I'll bring a couple examples and show you how insane the internals can get
Tiger I - Panzer III - Panzer IV - Chi Nu Kai - Panther G - KV-1b 756(r)
M4A3(76) Sherman - T-34/85 - M3 Grant
