I expected you to stop whining and live in the present. Alas we can't all have what we expect, or want. There's no real need to insult an entire group of people for no reason.
Can we actually get back on topic now?
Here's the topic for ya, not that you or anyone else will say anything useful about it:
1. If players are allowed to merge accounts, they gain
huge benefits over a group of people simply coplaying on one account,
and over people who simply play their own accounts in a tribe
2. It is extremely easy to counteract this, by restricting any IP address to any one account. If someone logs into their account and then another from the same connection (maybe have a time period here, such as 'within 1 month') it should flag the mods for investigation/banning.
Dawolf85's weak example about VPNs or dynamic IPs can be safely discarded, it affects virtually zero legitimate players (Show me some stats on how many people have ever been flagged for connection sharing accidently by a dynamic IP getting changed to one that has recent tribalwars history lmao)
