LOL i thought it was possible as you said, but you know, when a GM reply in that way it's also hard to comment again and reply sansibly.
Adding a simple sprite ID to the code of an item it should be done in what, 5 secs overall? the legendary weapons are how many? 20/30 items?
GMs says it's question of priorityes, i don't agree, just beacuse it isn't nothing of complicated to do (i did it in other private servers as responsible); as you said, it's an excuse, i think it's more quesion of give reasons to BUY the valk ones. I do not understand why not tell the truth , it is more transparent to the players and do not trigger even such discussions . Profit think is clear and understandable , just be honest .
