If they wanna implement that, there are a couple of things that whould help a little.
1 - All chara can spawn at friends hs.
2 - You can't spawn chara on your hs.
This don't "solve" the alt problem, but the Alt problem involve also the friendship and that's bad.
If you can't spawn your alt at Your fire, it need at last a friend hs and a hermit can't have 500 alts. But a town can, and towns are who uses it, mostly. So this solution is too soft..?
Then, remove the hs system and bring it back to previous worlds.
But then no one can start toghether. Like in old worlds.
...so, a step back? All we know that it was worse.
Back to present then. How to solve alts problem?
Remove the chance to have more than 1 player at account.
"Then there will be account spamming!"
Memorize the client to the pc, like most games do now.
"But it's a client feature. Clients can be easily hacked."
...
Then, instead of "solve" a problem adding more problems, better leave it as is it now and work on the game mechanism. Alts aren't a huge problem if they can die in any vault and if they need to login to preserve the claim.
This game choosed to let players create more characters, so is a feature, not a bug.
It's annoying but we can work on make it less annoying, fixing everything else.
I really don't see the end of the alt system itself. Fix all what's around it will be enough good.
AND what's more important...!
Did my english improved a little...? ò.ò
