Mission tables in:
WOD: Was kinda fun at first, because it was a new thing. But after a while I came to the conclusion (like most others) that it was a mobile-inspired bs thing to keep you occupied. Add to that the whole circle of getting a follower, lvl them, gear them, etc was slow and boring. By the time Misson Table Part II: Ships came out, I was already bored (mind you I did everything, got all achievements etc).
LEG: So basically the same thing, too slow and also as an altoholic felt kind forced to do them because the rewards were too good to miss (paragon reps alone) but I really didnt enjoy them. All this recruit, level, gear, equip it just wasnt worth the enjoyment/time.
BFA: I can accept these mission tables, and if they continue with this in SL i'm okay with it. Basically requires not much effort, and the rewards arent great (neither should they be) but a small bonus to rep, gold or AP is fine.
I wouldn't mind seeing mission tables in future, post-SL expansions, if it's been revamped to be something other than mobile-bs.
