Wait lol you are basing your opinion entirely on one single test (ever heard of RNG?), that was even favoured towards JLI's strength in its unnatural setup?
Apparently you did the same for your claim that JLI are performing similar to Obers, which isn't true.
I've done a small test with multiple types of engagements and the Obers are clearly better in all types of engagements with any level of veterancy.
This is the outcome of these engagements against a Penal squad in comparable cover at medium to long ranges. Note how the Obers barely lost any HP in these engagements (the vet3-5 squads were at 95% hp before they started healing) while most JLI squads took at least one model loss and a significant amount of HP. They took significantly longer to kill all enemy models.
Based on this I'd say JLI are at about 80% of Obers' combat power at most. That's not counting the Obers STG44 upgrade nor the bundled grenade. This would put the JLI price at about 280MP and 55MU but nowhere near the 340MP you claimed.
jagers still are infiltrating squads and have other abilities to contrast that of penals or obers... theyre the equivalent of a mortar or a sniper requiring screening in order to become effective... maybe 340 is a bit too harsh but note that its original price was 300 and it was still better than pathfinders then... even without performance buffs
