Is it me or is the vet 3 t34-76 underwhelming? If I succeed to keep it alive that long, it than faces better armor, which kill it with ease. In my opinion , they are designed to be used in massive formations. Which is a fine and pretty need design, yet why are they 100 fuel than? They cost to much..
That is because vet3 T34 isn't really that much different then vet0 one.
Its all about the armor vet axis tanks get.
Allied mediums have pretty underwhelming vet going for them and unless vet1 ability is good, the other 2 stars are pretty irrelevant.
You get better mobility and better RoF.
Axis tanks get that too plus in some cases huge armor buff or in other armor+hp. That makes a difference, RoF buff on inaccurate, low pen gun isn't bad in itself, but it certainly isn't as impactful.
Vet2 P4 is great, vet2 T34 is still meh. As a side note, USF shermans also do not have amazing vet, but pretty good out of the gate utility and the ability to actually FIGHT EFFECTIVELY at least 1 target group without the need for driving over it makes them incomparably more effective then T34.
