I'm sorry know nothing about? You do realise I've played since Guild Wars Prophecies release. And since when is 'Reintroducing' a substitute for something that should be in there in the first place.
But I digress, you want me to 'research', heres some research. There are 1,319 skills in Guild Wars 1 through all expansions. If we take away all those from expansions, that's 212 + 30 elite skills. So we have almost a rate of septupling the amount of skills. From my calculations there are 21 skills per class in GW2, there are 8 classes so that's 168. Add 3 skills for the 5 races and thats 183. We septuple that that's 1281. A large number indeed but if you remember that you have to stick to those skills then you're fucked. So say my character is a Charr Ranger (Which he is). I will always be a charr ranger and cannot change to any other class or race. So I'm restricted to my 186 skills. And yes, I could easily make a new character and start again, but who has the time?
And another, thing. Missions. Missions are just so fucking easy. They're about 12 seconds long and don't even require a restart. If you die, you come back to life with basically no penalties, a -15 health debuff that basicallyruns out once you reach the enemies anyways. In Prophecies the missions were long, interesting, set up a nice backstory and at some points, really really hard. I remember that fucking mission before Abbaddon in Nightfall and being stuck on that one for ages (Yup, I suck at MMOs). But I have to admit I actually liked it because it was a challenge. Putting enemies with 10 times the normal health and calling it a 'dungeon' doesn't make things any more interesting.
Look, I'll give you the benefit of the doubt and apologise for this rant and I probably should research stuff before I go on about stuff, but I certainly don't know 'Nothing about' Guildwars. Guildwars was my first love and always will be. Some people like the second one, some people don't. I am on edge between liking it and disliking it, I like some parts of the game, but others (A year of grinding to get a weapon with fire effects) I actively despise. Since you've informed me of this 'expansion', I have certainly changed my mind and yes, if people want to get it, I'd definitely recommend it for $10.
I for one hope they do Cantha.
