Tiger (H) Research Path

The "legendary" Tiger tank found in World of Tanks isn't very legendary. Thanks to the Russian bias that's been around since the beginning of time, German tanks have been very difficult to master and believe me when I say difficult. One of the problems with the Tiger tank is the fact that none of its armor is sloped as it was designed to withstand punishment and not deflect it. This was the last German tank that had the "classic" tank look as afterwards, German engineers copied the Soviet T-34 medium tank and incorporated sloped armor into their tanks (i.e. Panther and King Tiger). Alright, let's get on with it shall we?

Again, I'm going to assume that you magically didn't/couldn't/wouldn't research some of the shared modules.

1. Gun: 8.8 cm KwK 36 L/56
2. Turret: PzVI-Porscheturm
3. Gun: 8.8 cm KwK 43 L/71
4. Engine: Maybach HL 174
5. Engine: Maybach HL 210 P 30
6. Engine: Maybach HL 230 P 45
7. Engine: Maybach HL 234
8. Tracks: Breitketten
9. Radio: FuG 12
10. Gun: 10.5 cm KwK 42 L/28
11. Tank: Tiger II

Seriously if you are still considering using that 105 mm on a tier 7 heavy, you need to rethink your strategy. Only the strongest HE guns are effective for anything past tier 6. I strongly recommend that you use either the 75 mm stock gun while you grind to the 88 mm. You should have already unlocked that 88 mm from the VK 3601 (H) but in case you didn't, the 75 mm will have to do. 

Also, keep in mind that the stock tracks can hold practically everything so you may want to research it last. The new tracks does let you turn on a dime slightly faster and thanks to the extra load limit, you will feel your tank to be slightly more mobile. 

As usual, aiming for the best gun should be a priority as it will help immensely with the extra penetration and accuracy. The Porscheturm is also something you will want to get soon as the stock turret simply looks ridiculous and everyone will instantly know that you're driving a stock Tiger.
