The Tiger I and Tiger Ace are probably the best heavy tanks available. They are vastly superior to anything cheaper and about as good or better than anything more expensive.
Only once vet3 with the ROF bonus, and only the ROF, which Pershing is pretty close. But Persing is way more effective because of speed, speed, speed.
In the WC2019, killing IS2 is near impossible with the armor bonuce and faster retreating speeds and then click self repairs. I havent seen a IS2 kill in final rounds. Yes Tiger dies and dies.
Tiger while most commmonly used, is more of a force of hand. A unit with decent AT and good AI aoe. Something AI like shermans can provide for cheaper and USF used to good effect.
Panthers have gone missing in top tier games.
Brumbar no more too.
If this is not indication for Relic to look into T4...
