So, I guess reintroducing the spire set was not an accident? At least not here on beta?
In which case I have to tell you: It is a mistake!
The set has been proven to be a mayor balncing problem time and time again. For over a year, players have repeatedly pointed this out on every world and on every forum. And over and over again, we got the answere: "The problem is knows, we are working on it. "
Except evidence suggests otherwise. Removing the set from the tower helped to stop the problem from getting worse. But is does not solve the problem. There is still a scroll problem on every single world. And even the gum and bismut problem has not been fixed, despite the fact that decay should help fix this much sooner.
When the merchant was first announced, I thought this was supposed to be the long awaited solution at last. And I was honestly positively surprised. Because I really do think that merchants in combination with a normal trader could be an effective solution for current and future trade imbalances. But then it turned out that the merchants are not meant to combat such trade imbalances at all and there is no solution in sight. And now the spire set is reintroduced. It just sends all the wrong messages.
I may not like (most) artifacs in the spire, but at least they are only useless for the mayority of players, not actively harmfull for the entire game. And the bears wich should be coming next are one of the two artifacts that are actually great to have in the spire. So stopping with the artifacts now is very much the wrong time.
So please, do not let the spire set go back to live worlds !!!
