this has been announced/posted by blizzard that these will be the new bg brackets and levels required for the bg, personally i think its better as at a lower level you can do a larger variety of bgs which will get more people in pvp

The clash between the factions has also never been so hotly contested: Battleground brackets now match up teams more evenly. The new brackets span five levels each, except the final bracket composed of level 85 players:
10-14 30-34 50-54 70-74
15-19 35-39 55-59 75-79
20-24 40-44 60-64 80-84
25-29 45-49 65-69 85
Fighters can also join the battle in Arathi Basin, Eye of the Storm, and Alterac Valley at an earlier level than ever before:
Level 10 - Arathi Basin and Warsong Gulch
Level 35 - Eye of the Storm
Level 45 - Alterac Valley
Level 65 - Strand of the Ancients
Level 75 - Isle of Conquest
Level 85 - Battle for Gilneas and Twin Peaks
These changes should offer players a more consistently competitive experience in the Battlegrounds as their characters level, as well as provide for more exciting PvP conflict than ever before. Are you eager to try 35-39 Eye of the Storm? How about 45-49 Alterac Valley? Perhaps you'd like to cut your teeth on a 10-14 Arathi Basin.
