I will start by saying that Monster is my 4th choice. I can handle one or 2 pro Hunters, but not an entire crew. That said, seems even the most casual pubs have learned enough to blitz Nest matches every time. Bucket can deploy Sentries and walk away (pretty broken I think, the only deployable with infinite duration), and Eggs are affected by the Damage Amplifier & Weak Points.
Additionally, you can be domed and kited at the end just long enough for Assault +1 to reach the remaining Egg and nuke it. To top it all off, Eggs turn to paper machete when Hunters hit Tier 3 (complete Tier 2). What do?!
