If you think about it, and realise that the strength of the Tiger is not it's "invincible armour" or the 88Kwk, instead it was in it's employment. Successful Heavy Panzer Battalions that employed them used other Tigers in support, and they tried as best as they could to use the Tiger's main advantage, range.
When the Tiger appeared on the battlefield, it was indeed a phenomenal tank, but not because it was invincible. It was because the enemies did not have a comparable tank. That is why the development of the Russian T-34-85, the IS-1, and the SU-100 + 152 arrived. They were there to combat heavy tanks.
In the end, the Tiger's did well because their crews were well trained. But, shear numbers, lack of supplies, and parts doomed them.
I think the Tiger is about as good as it should be in this game.
