Here's an extract from my era-go thread, on rebalancing it, before you say anything about why it should be buffed and not nerfed go read the original thread-

"I'll give you a few options of what I personally want to do with the PBP. Make it 15 damage max, (2 damage per bullet default, 3 perfect, 5 bullets, 25 clip same freeze), 12 damage max, (4 bullets, 2 damage per bullet default, 4 perfect, 24 clip, 6 shots) And 4 bullets, 20 clip, 8 damage per bullet not stacked, slightly higher fire rate(means the gun can shoot faster), notice the word slightly, not major."
