Hello,
There are 3 dailies for battlegrounds : (A) "Win 3 battlegrounds", (B) "Participate in 5 battlegrounds" and (C) "Earn 1000 points in battlegrounds".
Time required in order to complete these objectives is pretty unbalanced. While you can finish (C) in 1 or 2 Battlegrounds, (A) will take 9 battlegrounds on average. (A) takes longer than (B) which takes longer than (C)
What I suggest is that (A) requires 2 victories and, on the other side, (C) ask for 3000 points. (A) will still be a bit longer than (B) and (C) a bit faster than (B) but not with such a big difference.
