And by penalizing jumping by making high precision shots impossible while in midair, you relegate the sniper to a 'mech who uses positioning and throttle management rather than "mad hops." The sniper would pay for his precision by increased exposure needed to pull off precise shots, risking damage from 'mechs who are engaged in closing actions. This would furthermore encourage the rise of bracket firing weapon groups - taking secondary weapons that can be used in close combat by multirole 'mechs, which are the bread and butter, meat and potatoes of Battletech. Jump sniping shouldn't be impossible, but you should hit "a mech's center mass" at 300m, not "a mech in the face."
Furthermore, the modifications the devs have on the slate for jump jets currently (increased heat load for long burns, leg damage for long falls), seem to inflict far, far worse penalties to 'mechs who use jump jets to maneuver, close, and escape than 'mechs that use them to crest hills.
The root and core of the game's problems are multiple high damage weapon systems slamming into single components. Nobody is advocating for the removal of group fire. So you have to spread that damage somehow in order for the game's core damage mechanics to be meaningful above the very lowest tiers of play. Inflicting gross heat penalties that make PPC use impossible for anyone without jump jets to dive behind cover and cool down makes the problem of a single dominant top tier tactic worse.
No penalty on the back-end of a jump sniping maneuver, as the mechanics currently stand, can both impose a high enough cost to put other tactics on the table for equal consideration without penalizing a jumping 'mech so badly that it's not possible at all. There's just no way to balance the risk-reward ratio without lowering the reward.
Also, even if jump jets were removed from the game, precision FLD alpha strikes from 500m would still be the top strategy. Targeting jump jets and specific chassis don't address that problem at all.
I just thought I'd like to highlight this statement...

I find my torsos sloughing off in one salvo to be way, way more annoying than occasionally drifting a shot when I'm piloting irresponsibly.
