Roundup on critical hits:
Currently, there's a chance (randomness #1) a weapon that hits an unarmored section causes a critical hit. A critical hit does damage to a random (randomness #2) item in the section (e.g. a weapon, ammo, ...) - the more critical slots the item occupies, the more likely it will be chosen of all items in that section to get the dmg if there's a critical hit.
ATM, engines are invulnerable - they take critical hits (according to Static1Shot) but when they have 0 health left, nothing happens.
Note there's a non-random damage to internal structure when you shoot at an unarmored section. When the internal structure is destroyed, the section is lost (-> "component destruction" bonus) and so are all internal items in that section.
Suggestion:
- Every shot should case a critical hit (remove randomness #1), but the critical hit's damage should be adjusted so that average DPS to internal items is not changed.
- Keep randomness #2, that is, which item is damaged when you hit the section is random.
- By keeping average DPS to internal items the same, you couldn't really(*) tell the difference between the current implementation and my suggestion.
- In addition to that, introduce critical hits that damage the engine. When engine health is 0, mech is destroyed.
- Raise the engine health to 40 pts (from 15).
(*) There are slight differences, involving the granularity and distribution of critical damage. But I don't think it impacts game play at a noticeable level.
I've suggested this before w/o removing the randomness (just engine crits), but eventually realized "rolling dice" to take down a mech is silly. From a TT perspective, randomness (dice) is the way to go, but you don't need that in MWO.
Effects of suggestion:
As a table.
- The columns "<mech> CT death" refer to how long it takes to destroy the internal structure (unarmored) of the CT using only one instance of a weapon.
- "engine death" refers to the suggested engine critical hits with a 15-health-point engine, that is, how long it would take with the suggested non-random engine critical hits to take down the mech - if there was only the engine in CT.
- "health 40" refers to an death by engine critical hits with a 40-health-pts engine, as suggested above

As you can see, this suggestion only buffs MG and LB 10-X AC, but also gives the devs another option to balance weapons. Also note due to shotgun spread, the LB 10-X AC does only reliably hit one section with all pellets at about 50 m (AWS CT). At 100 m, the pellets spread across both side torso and center torso, reducing damage to engine.
Btw: By removing randomness #1 it's also easier to understand than current random critical hit chances (25 % for one, 14 % for two, .....)
