DWG Rit gear help

Sorry to be a noob, but I don't really understand how weapons are modded to suit your needs? I've tried searching this stuff up and I didn't really get it. Do you need to find a base weapon, then add +5 energy for example? What does BMP mean by the way? Also, you don't think most frostway users bother with these weapon sets? If I understood correctly, Calista means the following:

Modding a weapon means taking a blue/purple/gold ( preferably maximum damage ) weapon, and add the mods you need to it.
Each weapon (usually) has an inscription slot, and two other slots ( prefix/suffix) that you can upgrade ( for example, staffs have inscription slots, a staff head, and a staff wrapping, sword have an inscription slot, a sword pommel and a sword hilt, etc).

In this case, the + 5 energy on the martial weapon would come from the "I have the power" inscription, granting + 5 energy to that weapon.

BMP = Bonus Mission Pack.
Its some extra content you have to buy online, allowing you to play some extra mission from GW lore ( Saul D'alessia, Turai Ossa, Master Togo's story, Gwen's story etc) rewarding you with a free max dmg fully moddable weapon after completing any of these stories mentioned above.

The reason why not many frostway people will bother with special weapon sets is because the people doing frostway usually aren't the most professional of the pve crowd, meaning that the average skill level of frostway you either succeed or wipe depending on the average group skill.
At that level of skill weapon mods do not really influence your fail/succes ratio.

Thanks a lot, you made it a lot clearer. With people missing the right weapon sets etc, do they even make it through still? Some scrape through,some make it look easy. Pot luck with pugs

And why should they, it works without this and the rits are running around with glaive 99% of the time so whats the point even. There is also that
