FC has given Multibox the official OK.
Some people quit. Some people didn't.
Those who stayed are faced with a changing face of AO. Some content is soloable, some is not. Tower wars and "open" or "mass" PVP is a completely different affair than what it was 5 years ago.
War is dominated by fast transport, extremely fast DPS, dropping a tower site before the defender can even respond. Defenders and defending, by-and-large, are limited to custom built gank-squads that exist for one purpose only: to eliminate attackers via un-defendable mechanics (AS or Nukes).
Question one: Do you like the new style of war?
Question two: If you don't like the new style of war how/what would you change, given that FC is unlikely to go back on their word regarding allowing MB?
My personal feelings are: I like how fast a tower site can change hands, but I don't like that there is literally no time for a non-org defender to get to site before it's fallen, except for at TL7 where there is sufficient time for a defence to get ready and transport there.
Regarding PVP, I'm disappointed that FC has not moved on this yet, but simply put, the insta-gank approach simply isn't fair, there needs to be some method of reducing incoming damage to a manageable rate so appropriate mitigation measures can be taken - i.e. instantaneous death due to nukespam/AS spam simply isn't cool.
Here are some ideas that I and others have suggested elsewhere, at other times. I don't claim these are the answer, but I hope that some discussion on this topic might produce some kind of reasonable solution and this is at least a productive starting point:
1. Any attempt to regulate MB must simultaneously validate the use of MB (FC simply can't go back on this after endorsing it for a couple years)
2. Limit the destructive power via either limiting the number of actions performed on one key press (probably difficult to enforce, and difficult to find real perpetrators)
3. Limit the number of active toons of a specific type (i.e. 6 NT's or 6 agents, etc.) per IP
4. Limit the destructive potential of any specific prof at any time (e.g. cap single hit max damage to 10% of max HP)
5. Significantly reduce the amount of subsequent damage any toon takes from subsequent attackers (i.e. 1-3 attackers = no change in damage taken, 4 attackers reduces all damage taken by 25%, 5 attackers reduces all damage taken by 50%, 6+ attackers reduces all damage taken by 75%) which would CLEARLY make it more difficult for people to /assist kill, and incredibly difficult for people to instagank anyone)
6. Alternately from 5, introduce some new method of stopping damage from any specific source resulting in rapidly diminishing returns if damage is taken too rapidly
7. Invalidate the /assist command
