Unsubbed -- HD didn't do it for me.
I'm not here to vent or anything like that, this is solely feedback that I hope Turbine will read. I'm not mad, it's their game and they can do whatever they want. I've been a turbine customer since AC1's launch in 1999.
I'm not happy with the skill trees and Helms Deep in general, enough so that it's not fun enough to play. My hunter does a ton of damage now (initially, but it's harder now with multiple enemies and extended battles), but I only have a couple of useful skills and ONE melee skill. I feel like I'm playing a Nintendo and mashing the A and B buttons. My Warden, while maybe being a viable character still, is no longer a Warden and not something I want to play. The Warden has a huge learning curve and I wasn't even proficient in all of his old combos, and then they change everything. The new skills make no sense and it seems you have to build them up as either a mini-guardian, mini-hunter, etc. Why would I want to do that?
The Helms Deep expansion itself, aside from not shipping on the promised date (seems like breach of contract and grounds for a refund to me), isn't very fun. Lots of running around and talking quests which seem like pointless fillers to keep you busy, not much combat. No fundamentally new monsters and the scenery is mostly things we've seen before too (Helms Deep itself is kind of neat, but laggy, and the Glittering Caves were pretty if confusing and unfinished). Quest lines are broken or confused. Forced to do mounted combat for a lot of it, which I hate. The "epic battles" are really just skirmishes with a couple extra buttons and a serious lack of instructions (Failing tasks that they don't tell you how to do, or walk the wrong direction, or just want to see what's "over there" and die for no reason! I wanted to do the engineer thing but I can't figure out how to advance and you really need to still manually fight the battles anyhow because the NPCs are too stupid). I don't like skirmishes either. I like quests, exploration, stories, fun with my friends.
Oh, and the whole outage thing with the Data Center problems. There's no excuse for those kinds of problems with a professional grade Data Center. I know you don't directly run the DC, but you did chose them and do pay them. I run one for a city and if my backup power failed without a *really* good excuse I'd be looking for another job. Same thing with my redundant Internet feeds and cooling systems.
