Interested in playing.

Hey guys, I've been thinking about Nostalrius for some time now and I'm very interested in playing. I'm just a little scared to and seek reassurance
.
I, like many others (even though Blizzard and their fan boys seem to think we're only a small, insignificant number), have become very tired of WoW. Since MoP I've found it less and less entertaining and I long for the old days. I started playing in late 2005 and remember the old days fondly. Now it's so ridiculously easy and dumbed down. Even the little things frustrate me, such as infinite throwing/ranged ammo, no longer needing to buy poisons, trainers no longer training and insta-learning things upon dinging. I don't want to pick a few herbs in Elwynn and find my character has dinged level 14 in a level 1-10 zone just from a few quests and herbing. I want to level *with* the zone, not far exceed the level range for it to be too easy, within 1/3 of the questlines. Even without heirlooms, just by mining or herbing and doing quests, you can far out-level the zone. Killing one silver rare can give you almost an entire level of unrested xp! You even get xp now for going afk to use the toilet!
I've looked at lots of videos online and this one is hands down the most recommended.
I'm a bit scared about my main WoW account getting banned, as I've spent quite a bit of IRL cash on it (subs since 2005, store pets/mounts and the new WoW tokens etc.). Is there a safe way to play without Blizzard catching me
? I read the FAQ where they say that Blizzard won't care if you keep paying, but what if they decide to care? I read somewhere else that the Blizz updater scans your files and can detect these second launchers and report them back to Blizzard who can then ban you, or worse.
I'm not very technical so I don't know if I can install a second version of the game to an external drive or anything, or use any sort of software to mask my IP etc., I'm not good with computers. Can a different folder on the same drive (I note you state c:\ instead of program files) really work, or will Blizzard still detect it? Could I use a secondary, external USB HDD that's perma-plugged in? My WoW installation (paid Blizz one) is on c:\World of Warcraft. I read somewhere that using Program Files folder could cause issues, so I installed the main game to c:\ directly. I have not downloaded or installed your version yet, I wanted to seek advice first as I am a noob.
I have a second PC, boxed up, from 2007 which is still in perfect working order and condition. I used to play WoW on it until I upgraded (for other games) last year. I last played Cata on it without issue, so it's viable as a gaming PC, still after all these years. If I load up the old PC, and it has no Blizzard software on it at all, and play Nostalrius on it, can Blizzard still see me, maybe by IP? Would they be able to see the same IP connecting to and old version server and the new one?
Finally, this is PvE isn't it? I saw in another thread somewhere, someone asking another person if they were moving to the PvE server when it launches, but that was only a week or two ago...this is the PvE one isn't it?
I hate and suck at PvE
.
Any advice would be appreciated.
