Hello, I'd like to point out that at least one of the daily quests does not fit to the types of units the maps are filled with: I have the "kill 10 support units" daily, and the only support unit I saw so far is the mind control device... which is sparsely placed on the maps... and either captains try to avoid them by hunting down the targets instead, or all of the group is after them, so there is one or two targets for all placers.
I also remember the japan/manga-themed campaign, I had a "kill 10 ranged units" quest and all maps were full of assassin and melee units only. So maybe it's possible to check the quests in rotation if they fit the event or should paused for a while.

Short update: after more than 17(!) hours constantly placing with 4 captains I gave up at 9 of 10.... this quest wasn't challenging, but not completable... especially if they're meant to be doable for the average Joe that only spends a reasonable amount of their time with games.
