Something I found myself observing about the content that has come up since F2P went live... it seems to me that, while the content shows a LOT of originality, there seems to be a pattern to almost all of it.
1) The length generally falls into the medium - long range. This is of most everything since, about, update 4 or so. It is reaching a point where I have a good feel for how much longer a quest is going to be without ever having played it before.
2) The size of updates, as regards quest content, is all very, very similar.
3) The majority of quests (somewhere before 50-80% I'd guess) rely on some sort of gimmick, as opposed to a straight forward dungeon crawl. While I have enjoyed almost all of these quests, and they are almost all very cool, gimmicky quests tend to have lower re-play value. JMHO.
I have sort of felt like each update is putting forward its 4-5 home-run swings and letting the small-ball fall by the wayside, and I just think that, while I haven't run into much that I have "disliked" the pattern is getting pronounced and it might be wise to shake things up a bit.
Not a condemnation, just an observation.
