This is nonsensical. Let's say Schine unveils a new weapon that does 0.1 DPS per block at beam distance, but "steals" blocks it destroys and drops them in your inventory. Are you saying you would replace every weapon block, even missile blocks, with this new weapon? If you think that weapon would dominate the new meta, I think you're mistaken. If you do that, sanely-designed ships 1/10 your size will trash you with their normal weapons and then take the blocks you salvaged off them out of your storage for essentially a zero-loss.What it boils down ti is what we've been saying, Salvagers salvage things but don't blow them up, weapons blow crap up but don't salvage them, if there was something that'd do both we'd all be using that to levels that would make you change you tune rather fast. The only reasonable combo of the two would be letting secondary weapons come in as effects when used on primary weapons in their combos. So you could do say Mps and make a Missile + Pulse + Salvager combo and salvage and nuke at the same time.
If you're saying that you could build big enough that eventually ship scale would make your damage comparable to regular weapons, that's true, but it's also equally ridiculous. If you have enough resources to make a titan exclusively using a block snatcher weapon, you could also have made a normal ship with 50x more DPS. Your expensive titan can be out-gunned by smaller ships, at longer ranges, for less cost, using normal weapons. Then, the smaller ship could use a small salvage array to eat your dead titan and take a bunch of your wealth.
If you really think I'm wrong, try it out:
Take a damage beam computer and link 400 1-block beam groups to it. Back it up with a secondary cannon computer with 400 cannons. With the group power penalty, this gets you in the neighborhood of the DPS/power I've thrown out in this post and others as an example for salvage beam damage.
Now, take another ship and use 800 blocks to make whatever weapon system you prefer.
Have a cage match with the two ships, and let us know how badly your beam weapon lost.
