I don't think there is anything bad with alt. You should be free to switch to any kind of character/RP/faction as long as you don't use it to screw people.
What is less accepted are fast-relog and dual log, but those are far less used in AOP, as you can't disapear when logging off in Phoenix, and need time to travel into any Phoenix zone. Beside that, the gain from doing it are limited too. It hasn't disapeared, but there is no team that center its gameplay around it, unlike some cessions in other servers.
I also think it could be good to have some/more features dedicated to the platoons/squads themselves, but it depends of what would be the upcoming features globally.
I know Shangalar mentionned that there will be some proper inhabitants in Phoenix and an extended diplomacy system in the future. Considering many members of the original team are silent since a few weeks, i wonder if the original goals are intact or if the purposes of AOP has switched to what the current most vocal members want. (which would be very unfortunate)
It would be awesome if the zone were areas in which you could spend most of your time, and in which you could have the various squads/platoons compete with each other for influence within the zone. They wouldn't PVP but compete in other domains, like questing/protections/enemies killing. So, the foreigner would only see that faction X hold X zones, but within the faction, you will know which platoons/squads of the faction are the most loved in each zones, and which get the most benefits from the zones. Or you could have some alliances between squads/platoon from different factions to take a territory from another faction they both dislike. So instead of contesting, one squad/platoon will take the zone while another will help, despite being from another faction and will get a % of the benefit.
IMO, most of it should apply to the platoons, as squads are far more versatiles, but it doesn't mean squads shouldn't have their own benefits outside of fights.
PS: It would be nice if you could see who is taking the zone, not only the factions, but also the platoons. It would encourage more some high level PVP team to join the fight if they know their favorites enemies is taking the zone. They don't care about the RP/the zone/the supremacy/fighting noobs/ they just want a good challenge.
