Which the last tournament proved wrong as even said skilled players avoided tier 4 like the plague
Well you don't need t4 to call in a tiger (non-ACE variant), just bp3. Probably has something to do with it. Tiger was built more often than all t4 units combined
You're also not gonna build a brumbarr when heavy tanks are dominating the meta. A) Tiger kills infantry more reliably, while also being great against tanks B) brum won't help you fight against an IS2/Pershing
That leaves out the fact that the Brum is probably best against the Brits, who nobody used. I think its strongest against them of the 3 because:
A) they don't have a heavy in the same "class" as the other 4 factions
B) fewer snares than US and Sovs.
C) They are BY FAR the most static of the 3 allied factions
D) the Firefly is the easiest to counter of the 3 allied TDs (D is my personal opinion, so I could be wrong)
