I currently play both WOW and Guild Wars 2. Right now there are no other MMO’s on the market quite as good. (I have played many others in the past) Below is a list of pros and cons for both games, but essentially why you should rather play Guild Wars in general.
+ Guild Wars is free,
- WOW is subscription
+ Guild Wars graphics are simply better
- WOW Legion has much improved graphics and the cartoony style suits the game but Guild Wars 2 still wins this department.
+ Guild Wars 2 has new content ALL THE TIME in the Living Story FOR FREE. The development so far since HoT has been interesting and engaging. You can also replay the Living Story episodes to catch up. Characters are believable and the script has improved since early days.
- WOW’s content and lore is still amazing, but the expansion packs do cost.
+ Guild Wars quest system is still the best out there. The dynamic quests and even just what the player are required to do in certain quests are a LOT more exciting and diverse than WOW.
- WOWs quest system is like this: kill x number of monsters, or collect x number of items, rince repeat over and over again. VERY STATIC and monotonous.
+ Although Guild Wars has less active skills to work with in game, the main and offhand weapon combinations make it more diverse and this mixed with your traits and mastery make creating and using your build very fun, especially in PVP.
- WOW has more active skills on your skill bar, but again you just pretty much spam certain skills at certain intervals to get the max damage/effectiveness out of it. There is really no diversity or complexity behind it. My retribution Palladin is level 100 and I have been using the same skills all game so far.
+ Guild Wars 2 PVP is simply the best there is. WOW is nowhere even close. The mechanics in Guild Wars 2 PVP (and combat in general) are extremely rewarding, fluent and exciting. In WOW, you pretty much just spam you skills till the enemy is dead. (Yes PVP requires a little more tactic and timing of the use of skills) But in Guild Wars 2, you can also dodge to evade attacks based on a stamina bar, you can also block depending on your weapon selection and class. It is a much deeper experience than WOW, and I am only talking about sPVP here. WvWvW is a whole other scope of large scale PVP combat which the only other game I can think of that comes close to it is DAOC or WAR: Online.
+ WOW is a grind for gear based game. If you want the most powerful items, be prepared to spend most of your life playing this game. Also, every so often, they introduce new weapons and gear that is more powerful than previously. So you have to keep grinding to have the best gear. Some people enjoy this and thats fine, this is for the hardcore crowd.
+Guild Wars 2 grind is more for cosmetic looks of weapons and gear. Yes, the Legendary weapons and armor have slightly better stats the Ascended and Exotic, but that is not the main reason people want them. Just have a look at some of the legendary weapons, they are stunning.
The twos department that I can think of where WOW actually beats Guild Wars is the sheer size of the WOW universe, in terms of map and zone size, a more importantly (and this is what I dislike about Guild Wars 2 the most) is that the zones in WOW are almost completely seamless. When you cross over into a new zone, there are no loading screens, it really feels like one gigantic world. Where as in Guild Wars, yes the zones are big too, but you have to go through a portal to enter a zone next to it, which takes the immersion out of the experience a bit. Also, when opening up the map in Guild Wars 2, it looks like you are looking at a giant sliced cake (all the zones cut up into squares). I understand it was designed this way because of server limitations, but I really feel after 5 years of the game being out they can afford to design more seamless environments.
-To get around in Guild Wars 2, you either run or use Asura portals all over Tyria for a quick transit and a small fee.
+ WOW has supercool mounts and this works because it goes hand in hand with the massive world I mentioned above.
Both are superb games, but Guild Wars 2 was designed for longevity and the millions of people that still play the game are testament to this.
