it has? what to?
15 perks, half of the tiger's cost
You also need to keep in mind that our Tiger is a 1942 tank, where it should be fighting T-34/76 and and the 75mm sherman. M4a3(76), Pnzr and T-34(85) are later models that the TigerII would reign supreme over. The Tiger would still be superior, just not as successful.
In AHI I didn't feel that the Tiger had any more or less superiority over the Pnzr than it does now. Think about it, HTC has made no changes to either tank since then, only new tanks have been added.
IMHO that the freaking TigerII (a.k.a. King Tiger) if not bombed would freaking reign supreme over Tigers...
Those panzers and T34/85s are still extremely vulnerable to the tiger. Both need to get into the range that the original PnzrIVH from AHI has to before being effective of ANY sort against the Tiger (only people that are new to the game, stupid enough to allow a tank to flank them, or is being overrun by armor will let this happen). the 76mm Sherman needs to make it into some sort of close range also. I was in a GV battle of one enemy tiger vs me, and two others in M4A3 76s. I had to get 700 yards off its flank in order to kill it while the other two shermans kept at distance to distract the tiger. The only true tank the Tiger must fear that is not another tiger is the British VC Firefly which you will NOT see as much of due to the new perk cost.
Here's something for you guys. Study your tactics. GVing is a tactician's sport. Yes i killed the tiger but not before my two allies in their shermans fell to its guns and immediately afterwards i was killed by a sherman 75. The Tiger remains supreme in all aspects since the perk update of the Firefly and will always, in general, reign supreme over the battlefield.
Edit: here's another thought. dont be stationary in a GV fight. with all tanks, mobility will allow for kills over a stationary fight and this includes tigers. ALSO, learn the terrain before deploying a Tiger (A Gver's best weapon in my opinion... If you know the battlefield better than the enemy you will ALWAYS be granted an advantage in a GV only fight). if there are groves of trees everywhere limiting sightlines and mobility it is preferred you use another nonperked tank... although with this low visibility and limited movement of heavy armor, vehicles such as the T34/76 T34/85 and M-8 would be able to rack kill streaks up and up if GV'd correctly...
There's my two cents

even if you disagree with the tiger talk, then at least read what i said below it
