Guys, heres the deal:
Before the new version (ie, the increased perk cost), it was "oh, a tiger upped? Hang on, I'll grab a firefly". Either the firefly was perked far too low, or the tiger was perked about 3 times as much as it should be.
Now what would you rather have? Hoards of tigers, or a reduced number of fireflys? htc HAD to do something, it was insane. People were racking up 30+ kills before being taken down by an A20.
The panzer and the M4(76) are both capable perfectly of taking down the tiger. Simple formula here, and I'l even share it with you...
2 shots to turret it + 1 shot to kill the engine when it turns to run = you get a kill on a tiger.
In real life, not even firefly drivers gave the tiger as little respect as it got when we had 4 perk fireflys. Stop whining just because you don't want to shell out some perks for a gun that owns, and don't want to pay extra for some armor.
