Factions boring? Nope, not for me.
I started new characters, professions that I've never played before (a Necro and an Ele, the new Factions professions didn't interest me) and having fun. I have money and stuff in storage but I didn't dip into it. I'm doing the things that I did when I first started out in GW Prophecies - exploring (scenery in Factions is fantastic), saving for armour/weapons, reading npc speech, watching cinematics, etc. - basically taking my time and enjoying myself.
New campaign, new characters and a lot of learning of skills/spells, their abilities, strength and weakness are keeping me excited, entertained and busy.
The only thing that I do find boring are some of the quests that require you to go here, there and everywhere - just to deliver a message or something. There was only a small handful of these type quests in Prophecies (e.g. Blood and Smoke) that I hated, whereas Factions has much more. Going back and forth and back again, across the city, to speak to npcs isn't fun. However, coming cross mobs to battle along the way does help take the boredom out off doing such quests.
Also, I've always been 100% PvE. My only exposure to PvP was the little bit where you leave Pre-Searing. I've never felt the urge to try PvP in Random/Team Arenas. Recently, I brought my Tyrian Mesmer over to Cantha, to see how she fare in the new land. Having reached Fort Aspenwood yesterday, I thought I have a go. It's like PvE and PvP all rolled into one, and I'm Loving it! Win or lose I was having a great time, and was entering battle after battle. I wasn't too happy with some of the AFKers and quitters who joined in a couple of battles, but they didn't ruin much for me. If it wasn't for work, then I would have still been there grieving the Kurzick team.
Overall, Factions is keeping me very entertained in many ways and I'm glad that I bought it.
