I recently got the Tiger and I enjoy it a great deal. It's not a breakthrough tank, so it would be ill advised to spearhead any offensive. For that, I understand the Russian heavies are better suited. However if you can play in a patient manner, not take risk and you have a good feel of the battlefield, the Tiger is also a very rewarding tank to play.
I have earned the highest average XP per battle than other tanks, but the Tiger is not a money maker. If you lose a battle, you'll break even. Have a great battle and stay alive then you might see 20k, so on average, probably 10k.
I plan on staying with it for a long time before moving up the King Tiger, going to max out the crew and upgrades before I do. The 88 /71 is not one of the most powerful guns in the game, but the high velocity and long range make it fun.
Ignore those that will say this is just a sniping tank. It's best used at long range, true. But depending on the dynamics of the battle, the Tiger is good for close support. For example:
In one Malinkova battle, with each team having half the tanks remaining, we began our counterattack. Three medium tanks were able to breakthrough the hill pass and started making their run. As the only heavy left and TDs and SPGs hanging back at base, it was time to take action.
I began crossing in open field to engage the IS and T1 left at their base. while the mediums finished off a few stragglers on the way. I fired away the other heavies concentrating their fire on my while the mediums approached, flanked them and finally helped finish them off for a victory.
The Tiger soaks up quite a bit of damge, deflects little and as a result module damage is frequent. However a toolbox keeps me going
Good luck out there! In-game name is Rags
