I'd like to see a post rate of one per few days at minimum; I don't want the RP to feel rushed, but I don't want weeks to go by with nothing happening. There's no true post order either.

The weapons are self-designed to cut myself a bit of slack, honestly, but all the FRAMEs will have been prefabricated by me. There's four you can select right now, but there will be plenty more on the table after assignments and milestones are reached in the IC. Same goes for the subsystems. 
New FRAMES that appear will gradually increase in performance, so you'll feel like you're getting "beefier" the longer the RP goes on. Something to work towards, and all that.

I don't have a problem with melee weapons or shields as long as they make sense and are used realistically (within the suspension of disbelief of mechs duking it out). So things like pneumatic jackhammer-esque spikes could be cool. But big slabs of metal simply won't penetrate armor, and in most cases, you're just better off shooting a gun. You don't see Bradleys with axe-turrets anywhere, after all.

Weapon tech is comparable to modern-day, so ballistics are going to be the gold standard. Prototype energy and railguns aren't out of the possibility down the road, but that's endgame territory.
