Well I have a few opinions some bad some good but I really do enjoy the game!
The good side: Well the best part is the whole new dramatic scene from Cantha. I was shock with the huge environment. The new armour also looks so asian which that was quite a good job for thinking that up! I also like about the part with the pvp upgrade. The Guild Alliance system was a excellent idea it would really help the players who really help on there quests and missions. The best part about the excellent upgrades with the pvp system was the territory part with the two factions. The two factions that control multiple of parts of land. The two factions are called the Luxon and Kurzick. Luxon and the Kurzick try to take each others land by doing pvp. The new professions also were fun (Assassin and Ritualist). That looks like that Cuts it for the good side of this game.
The bad side:It was repetitive I started getting the same feeling when I first playing Guild Wars. When I was reading another review of guild factions some one said they try making game so hard we can't run it or avoid the enemy's. I agreed with him too there is just to many updates to rearranged the ai so it just gives us less options to beat a mission or run to another place(This also happens around the original guild wars too).
Thats my full opinion of the Guild Wars Factions. I hope everyone agrees with my knowledge that i gave out.
