That is ridiculously easy to fix...
If you want to fix bind rushing you basically have to make the already hefty death penalty worse. If you disable immy healing you basically kill powerleveling and helping friends with vastly differing levels. On the racewar Zeks people basically stayed at 51 so the level 60 players couldn't touch them.
And even if you fix those things: people are most creative when they want to find ways to be a dick to each other.
And I'm not convinced about the "game centered around poopsocking" argument. They design lots of stuff to do, and for it to take a long time, it is up to the players how much time they put into that.
It's not about only poopsocking, it's specific about "because there are no instances/shards only one poopsocker can do specific content at a time". And of course everyone wants to get the best stuff, because on PvP servers you have to be competitive with other people.
Also, a story from the Kunark era: On the racewar Zeks the dark team had no rangers, druids or bards. This of course included stuff like tracking, and for the Sebilis key you had to track two specific mobs. So the dark team basically got shafted here. Only a select few knew about ShowEQ then. In the end the dark team paid some druid to track the mobs, the other players found out about it and then insults and death flew around until that one character was basically not logging on anymore, as the other players made life hell for that one character who was branded as a traitor.
Of course it was horrible for that person, but basically that was the way the community policed itself. This wouldn't work anymore today, because there is no "community" anymore. Also, the basic game design later needed bards for resists and stuff, so X-teaming became the norm.
