Vet 1 stuff
4) You get already vet1 after killing 14 gren models for example, without getting self damage.
5) You get vet 1 already after 4 shot(hits) fights vs enemy PIV, without getting self damage.
6) You get also some vet, when you get damage from enemy.
So you can get fast vet1 for T34. It is just to give enemy a chance to see and react, that you got new t34 to ram your units.
So if you look close to this change, it is a very very small nerf to a very strong + cheap ability.
Killing 14 grenadier models sounds super easy, barely an inconvenience.
