This expansion is really nice (I won't get on with positive elements), but I would have three concerns : Empty maps. Yes, they are beautiful, but the lack of meta events turn some regions into a real desert. Some areas are a nice surprise (the snowy parts of Desert Highlands with the underground ruins are great), but are not multi-layered and the larger-than-ever size seems to be a consequence of the newly introduced mounts, rather than a real effort to put surprising content. Bounties. This mechanic is pretty fun, but for a time. Apart from dailies and achievements, there's no point doing them regularly. Mastery points. I get it, mounts are the big add-on, and why not doing all the mastery tracks based on them. But, the way to get MP is boring. It's just exploration. Central Tyria MP were fun, when we had to complete events (Triple Trouble comes to mind). Too many mastery insights, really.All those concerns have a common ground : once we will all complete the maps, what will be next? For now, it's fun, because we're exploring a new/old world. Once it will be done, those maps will become a no-man's-land.
