BLU has access to a sleep spell (Acorn Bomb), an instant spell (Flying Sardine) and a spell that stuns and pulls mobs to you (Sticky Tongue). All three are easy to get.

The activity will die down as more and more players reach 50. You can either wait it out or learn how the game systems like tagging work.
