Change: Decrease kill experience reward of veteran USA Burton to match other heroes

• Resolves Hero units give little kill XP #2025

This change streamlines the kill XP progression of USA Burton with other heroes and infantry.

Before

ChinaInfantryBlackLotus
  ExperienceValue = 50 50 100 150  ; Experience point value at each level

AmericaInfantryColonelBurton
  ExperienceValue = 50 100 100 150  ; Experience point value at each level

GLAInfantryJarmenKell
  ExperienceValue = 50 50 100 150  ;Experience point value at each level

After

ChinaInfantryBlackLotus
  ExperienceValue = 50 50 100 150  ; Experience point value at each level

AmericaInfantryColonelBurton
  ExperienceValue = 50 50 100 150  ; Experience point value at each level

GLAInfantryJarmenKell
  ExperienceValue = 50 50 100 150  ;Experience point value at each level

Rationale

Originally the Vet 1 Burton gives twice as much kill experience as the other Heros for no apparent reason. It is not particularly harder to kill or more dangerous than the Vet 1 Jarmen Kell.

The Burton kill experience progression mismatches with the global unit experience progression, which typically looks like so: X X Y Z.

Another example of why I think "streamlining and uniforming values", is a super bad approach:

I agree that kill XP could be raised for the heroes(small value). I totally disagree with the streamlining.

Reasoning: These 3 heroes are very much different in gameplay, and vary in terms of how hard they are to kill. Lotus I would argue is the easiest to kill therefore should give away the least xp. Jarmen and Burton are much harder to kill, with Jarmen being the most difficult to kill in my opinion.

Black Lotus veterancy progression has already been improved. She can level up quicker. With self heal she will also be harder to catch like the other Heros. Additionally there is a pending change to increase her Vehicle Hack range by some around 30%.

You write Jarmen is harder to kill than Burton. I agree with this statement and it supports this change. Vet 1 Burton should not give twice the kill reward.

Rationale text is left to be added.
