GW2 is completely different from GW1. It really is dynamic content open to everyone at anytime at any level, as long as you are there. You dont talk to quest holders, you enter an area and an NPC is shouting that such in such needs to be done. You dont have to activate it, it just happens with or without you. So you can choose to participate or not. Also these events happen as a chain ov events. So at one point the dynamic event for the area might be X, then you come back a few hour late and its Y. Or you could stay in the area and complete the chain of events as they start. There are zones like in FFXI but they are very large. And multiple events can be happening at different areas with in the same zone. You get credit automatically from completing the events and you dont have to Talk to NPCs, and you get rewards based on contribution. As for what I said earlier about at any level, you get automatically scaled up or scaled down in level (not your true level) according to the event. So if your lvl 1 you can participate in level 80 content, and if you are level 80 you can participate in level 1 content. And you still get rewards/exp appropriate to your level. Keeping if fun and relevant to everyone, and not having BS like a small group of lvl 80s going to a lvl 40 event and facerolling it.
I know many people love FFXIV and pretty much no other games are on their radars, but look into what other games are offering sometimes. I see nothing wrong with taking good elements from other games and implelemting them in FFXIV. If FFXIV had the dynamic OW events GW2 is planning, then I'd be playing FFXIV and not writing this. As I said in my other post its really about providing good filler content. And everyone knows FFXIV has basically failed at this. Which hurts the rest of the game, becuase people can only do dungeons and primals so many times. Sometimes having things like a dynamic events system and minigames are a much needed and frivolous break from the same old thing.
