2. Destro population/bias - this is my real concern, as posted. On my server (Axe Bite Pass), Destro dominate any RvR's through pure population, and they have the edge in Scenario's too....out of the 15 or so I've done, we've only won 1 on Order. Since the game went into full release, I've never seen Order control a tier on my server. The High Elf zone on my server is getting quieter, and I have concerns that people are jumping ship to Destro already....
I think a large part of that is that a lot of the beta testers and a lot of the ex-Daoc players went Destruction. Another problem seems to be that for some reason, the Order players just dont want to go out and fight in the open, even on our server which has a population of High (order) and Full (destruction) most of the time, that "High" population of order seem very reluctant to go and take keeps. Instead they seem to spend most of their time doing the instanced scenarios, like BGs in WoW.
I've really got no idea why that is, they certainly have an almost equal population to us, yet seem to be stuck in a WoW mentality (instanced BGs) rather than a Daoc mentality (RvR and taking keeps).
Also as you rightly say, some servers have Low-High populations, or Med-High. Although looking at the server list just now, there are also some terrific looking servers, Burlok is on High-High I bet thats a decent server, Eltharion (think it was that one) is on Full-Full. (having said that though, as I mention above, the population is no use if it spends all its time in instances instead of RvRing).
Not too sure at this point what they can do about the servers with big population imbalances. Maybe offer an XP boost to the lower populated realm on that server or something, but even then, would that be enough to make people stop playing their characters and reroll on that server, probably not.
I just wish Order would get out of the instances and come take keeps more often on our server, populations are reasonably even on it, pity they dont do it really. A few guilds do try, got to salute them for that, its just a shame that 1 Order guild can get 8 members together and take one of our keeps, while a lot of the rest just go into the scenarios over and over. Just doing scenarios isnt going to get you control of a tier, need to mix it up and do all the aspects.
