There are so many requests to do this.  I don't think anyone has come up with any good reason not to, especially for modest changes like this.  But - never any acknowledgement from the devs etc.  Maybe there's a technical issue?

The problem is especially acute after weekly resets, when both weeklies and dailies are on the radar.  Can't get them all at once, so one needs to juggle logistics of what to pick up when and when to turn them in, which is complicated by some quests that share completion requirements so that they should all be active at the same time. There isn't always an efficient path to cycle through them, which leads to wasted time going back and forth to clear some quests and pick up others, and them returning to wherever they are being worked on.  Sailies in particular are hard hit with this, given the distances and time involved, and when they concentrated quests in the same places they actually can make things worse (although I still need to try the latest changes in these).

There were quite a few posters suggesting more full featured quest changes, some of which were pretty good.  Would be nice if some of the fundamentals of the game were addressed, not just more superficialities, so that all of the game could benefit, not just selected content.

yeah, 30 limit is a pain, with the lastest update I could not pickup all the sailies and bater quest with 1 run.

I did a count, 37 in total, 28 dailies and 9 weeklies
