should a stock mech in the game not be able to alpha once from zero heat and not shut down?
for example a WHK-PRIME minus its lrm10 cannot alpha its 4 erppc, does that not seem wrong?
By technicality and the lore definition of an alpha strike -- it is unsafe for almost all 'Mechs to alpha strike. It is expressly written as a rare, last resort from a desperate pilot that is either already on death's door or praying to escape said door.
That is to say...
That's when you alpha strike -- and even then chances are if your mech isn't sufficiently cooled, you probably will die as a result....by being cooked alive. (Temperatures of over "60%" of the 'Mech threshold uncooled in a 10 second period are dangerous enough to cause 1st degree burns to the pilot and over 63.33% can cause ammunition explosion if sustained for several seconds). The RNG factor of the ruleset is to create the chance possibility that said attack will be spread or tightly packed together thermally (as in did the pilot fire then pause and fire? Did the pilot chain fire? Was it truly alpha striked? Has this heat been constantly pushed?) If said damage/effects trigger, it's because the chance of pilot error (i.e. "ZOMG ALPHA STRIKEZ R KEWL") had occurred and said moron fired weapons too closely together, thus hitting that heat all at once rather than across 10 seconds, overwhelming the heatsinks and thus -- issues.
All said and done... In TT with basic rules, I mostly hit a shutdown regardless. In tabletop (Megamek) with heatsink thresholds (heatsink taxing) turned on, in 3 separate attempts with 3 identical warhawk primes...
1) Melted 1 heatsink, caused an ammo explosion, was injured and lost consciousness. Mech fell over on shutdown.
2) Melted 1 heatsink, did not cause an ammo explosion, was burned and did not lose consciousness. Mech did not fall over. Mech did not shut down.
3) Melted 1 heatsink, did not cause an ammo explosion, was not burned, remained conscious. Mech shut down but did not fall.
This was just firing the 4 ER PPCs.
Doing a true alpha strike, same 3 mechs but under a new start and perfect conditions (btw not moving on all instances).
1) Melted a heatsink. Ammo explosion. Was triple injured. Stayed conscious. Mech fell down. Pilot died during the next 10 seconds (due to the unarmed mech that I shot Stackpoling on me in an explosion during the next turn, caused from falling over after trying to get back up repeatedly when the shot I delivered removed an arm, side torso, leg, and all CT armor in a single blow).
2) Melted 2 heatsinks. Ammo explosion. Was double injured. Lost consciousness. Mech fell down. Cockpit was destroyed. Pilot died instantly. Yay faceplant.

3) Melted 0 heatsinks (miraculously). No ammo explosion. Mech shut down. Pilot stayed conscious and was not injured. Mech did not fall over. Was curious. Could not boot back up for 30 seconds. Pilot did take injury after 10 seconds of waiting. Ammo also blew up during that time.
So, yeah. Stock builds aren't perfect.

Even if they ~almost~ universally seem to perform better than MWO meta builds on tabletop.
