The only issue is that if you put them on par with Delve Boss weapons you come across the issue the game current has as it is, right now many shouts are for Delve Boss weapon DDs only, this will continue, with the exception of allowing RME120s to join as well, people who will likely have boss weapons anyways. I am not saying your wrong, your right, it is good to do it in a way that does not promote or allow more exclusions based on weapons, but that exact thing wouldn't solve much. An issue with SoA as a whole is the large gap between levels and weapons, which are not being made any smaller as it is. I know a few people with decently augmented Skirmish+1 weps which are excluded from Delve Boss runs, which are the only better weapons there are unless you want to count in high rank Delve weapons too, which are much harder to obtain without actually doing Boss runs as it is.
