Vet threshold; AVRE 45 KIA + panther and no vet 3

This game has a problem with some units being ridiculously easy to vet up regardless of the targets they are facing and some units needing to kill lots of units to even sniff late level veterancy. Obviously a heavy like an AVRE shouldn't be easy to vet up as it deals massive damage (albeit the mortar shell is very slow and has a long reload time) but in this game I got 45 total kills (1 was a panther) and I also did base building damage to OKW/Ost which isn't reflected in the kill count. At the 43:50 mark I get a nice shot off on 2 panthers side by side and do about 1/4 of full hp damage to each one. At 47:00 mark I take out 2 entire vetted PG squads with schrecks and that almost gets me to vet 3 but I'm still sitting there with about 15% to go. To recap, other than one blast that killed 9 volks, all my targets were high value infantry, tanks and base buildings.

There are other units, but this is the most recent that I have come across where you should have a chance to get and use highest levels of veterancy without having to kill for 20 minutes. Most games will be over before then and it makes highest levels of vet almost pointless except for 1 hour long slog team matches. This situation is exacerbated in 1v1 and 2v2 matches where there are less targets around per square meter of the battlefield and less carnage per player overall.

I don't think the AVRE is at an insanely high vet threshold but I do think a 15-20% tweak would be very welcome along with a look at each unit on every faction.
