Why the Metalmark is Awesome in Lancer Rpg 

Frankly I never looked too much into the Metalmark (and the Mourning Cloak for the same reason) because I saw the art and my brain immideatly went "alright, assassin frame" and moved on but I never realized that its tools aren't its main thing but more of an assistance to its decent base surviability, as you probably won't blow up just for not being invisible for a turn or two

The Metalmark’s Flash Cloak allows it to move between pieces of cover on its turn, or even approach enemies directly, while hidden, without breaking its Hidden status. Normally, if you enter an enemy’s sightline mid-turn, you’ll lose Hidden. But if you’re invisible, you’re always out of sightlines! This makes this frame the king of the Prowl pilot talent line, a set of talents that benefit from attacking from hidden. There’s even a part of the talent that adds a flashbang once you break hidden by attacking, and then lets you move away! If you only took the skirmish action on your turn, you can use your extra quick action to Hide once more, maintaining a stealth loop. Bringing in the Hunter pilot Talent, as well as the Integrated Weapon Core Bonus lets you swing with 4 Shock Knives in a single skirmish action, which, for the low cost of 4 heat (likely putting yourself in the danger zone if you have the Nuclear Cavalier pilot talent), you get to deal 8 unblockable Burn damage on top of 4 energy damage. The Shock Wreath can add an extra 1d6 Burn damage to that *and* blinds them! Enemy armor means nothing to this thing, and if the enemy fails its engineering check it will melt away at the end of its turn taking an extra 8+d6.

Id argue against it being an assassin mech and more of a gurellia fighter mech, running from cover to cover and setting up ambushes. And it's equipped with more tools to get out of a fight. With burn and ap weapons, they can dive in and out while mimimizing damage to itself. Or it can close the gap to deliver a flurry of blows

Flash Grenade is nice because you can really wreck Artillery-style enemies - if you force them to move, that's them missing out on any full action offense. Plus, yeah, potential escape tool from melee enemies with a bit of a Threat bubble.

Flash grenades are unreal with any kind of immobilization. Splash some white witch and suddenly you have a guaranteed repeatable effective stun. Pinning spire+flash grenade is a great way to shut down a dangerous threat almost 100% of the time assuming you're close enough. Two enemies grouped up? Run two spires and burn an overcharge and suddenly you've effectively stunned 2 enemies, no risk required. All this at LL 2.
