I think the biggest issue is that all this effort is worth like 2 days of VMW2s (3 a day). It's the reason I'm not really looking forward to doing it when I'm 50. All that grinding for 2 levels seems underwhelming to me. Toad and LoI are supposed to be questlines that take you through 30-40 and 50-60, respectively, not a bunch of missions that give as much exp as normal dailies, only 10x harder and time consuming, for a total of 2-3 levels and then back to dailies.
The fact that LoI came so long after 60 cap was released and pretty much everyone was already level 60, from doing 50 cap missions, makes it even more underwhelming. Makes me wonder if we'll have to do the same dailies when 70 cap is out and have a questline that feels more torturous than rewarding.
Level 1-60 takes roughly 2 months (for me at least), and if nothing changes in the future, if we get lv100 cap it will take a literal year to level 1-100. We'll probably still be getting Daimyo express at level 99, too..
