While I appreciate that GW2 is an MMO meant to play with others and I enjoy seeing other people and grouping up with them, it concerns me that if I'm not doing the achievements/collections as soon as possible, that I'll find it difficult in the future to get them done, so I feel pressured to do them quickly.
As an example, the new 32 Slot Bag and the Ascended Backpack in the map require groups to complete metas or bounties. This is fine now as the map is active, but in a year's time, getting these done will be much more difficult as newer content will be out that's taking up players' time.
Does this concern you as devs, or do you have any ideas in place to get people to do these events randomly in the future?
Zaishen Quests in GW1 were a good example of how this was preventable, as it encouraged people to do content they wouldn't usually do. Have you considered building a core system similar to dailies that encourages people to do meta events or bounties that eventually won't be desirable months/years down the line on a rotation?
