They are always compared with cheaper infantry, for obvious reasons.
Lol. There is only cheaper infantry in the game
. No one says that Shocks should not be the most powerful infantry of the game. What we are saying, is that they should go back to 2 cp and be just a little less durable. Shocks are meant to be countered by vehicles but they overperform a little against infantry. They are still relatively cheap for the power they offer. So, make them a little less durable or a little more expensive. 73 MP for one squad member is too less MP. One Pgren costs you 90 MP. And sure, Pgrens can be upgraded with powerful AT but that costs you a lot of ammo (120). Moreover, if you upgrade them, they don't stand a chance anymore to infantry, especially not vs. shocks.
