Relic weapons are designed to be powerful weapons that can be gotten by anyone, regardless of skill level, exchanging the 'skill gate' for a grind that gets you the second best weapon in the game.

Its an alternative for people who cannot complete Coil 2 (Or whatever the newest raid is at the time). It is not there for your approval. It's not here to be fast. It's here to give you a chance if you are currently not up to the end game raiding snuff.

I say this as someone who just got Coil 2 unlocked about a week ago, and who's unlikely to get High A. stuff any time soon.

If you want a faster weapon that is obtained through skill, then get into Coil 2. If you cannot do so, then don't get pissy because SE didn't make what might be considered by some a freebie (Skill wise) 'easy' enough for you.
