Living story is like modding a released game
The thing with MMOs is they get boring if they only make the same kind of content, like dungeons for example. I think it’s good they are introducing new and different modes of gameplay. If they only made dungeons and PvP changes this game would lack a lot of depth… it wouldn’t feel massive. Though, I think they are pushing it with these events that require 50+ people. It’s not a mod, it’s an update (not much difference between the two anyways…)
In other MMOs i’ve played they’ve never really introduced a whole new type of gameplay, they’ve always stuck to the basic concept of the game.
Maybe it’s because the likes of EQ2 and EVE have always had massive 50+ player events as part of the core of it – Raids and PVP full scale territory wars, whereas GW2 seems to be trying to create raids with something that wasn’t built for raids?
Expansion packs are mods too.
Who the hell cares. It’s fine. I rather have other content and fixes done but I don’t see these “mods” as broken in any way.
