I have been waiting a long time for this game to arrive, and am very excited for it. I just do not have the time I used to have to play MMO's. My free time to play is only on Saturday and Sunday during the day, almost all day (6:30am to 6:00pm)

Is it going to be worth getting into for that. The previous games I was always main tank for raiding guilds, I know I will most likely not get into the heaviest of guilds in that regard. Would a weekend mostly guild be viable in PvP at holding keeps and whatnot? I miss the days of DAoC and running out to defend my guilds keep and others in our alliance at moments notice while dungeon crawling.

I watched a Tamriel Foundry video earlier saying he thought there might be different duration on the campaigns. So there might be longer PVP campaigns that last a few months and then mini-campaigns of only a few days. Not confirmed though...

Sure... why not?

Yes, but you'll always be slower or less progressed than people with more time to play. But that doesn't matter as long as you have fun.

I would say yes, but not a lot is known about endgame content really. I've heard it'd take roughly 450+ hours to 'complete' a character and that does not include endgame content.

With the maturity of the community I believe there will be many "weekend warriors" since many will have jobs, children, spouses, and who knows, like a bowling league or something
