For something different I dropped tier 5 to tier 3 in the dz. In minutes I got killed by a dbag 4on1 and that's ok. Went back to checkpoint and dropped to tier 2. Came out and got slaughtered by the same 4man squad from tier 3. Since when does this happen?
If you want to try a lower ranked DZ, trying getting a second character leveled up. Some people go to level 29 and hang out in that DZ as there are no gear sets.
