I'm undecided, (Please have mercy!) so I made a small list of Pros for each team.
Team Tree Pros:
It started as a very well deserved jab at Twitter. Got to love it for that!
How can you so no to Terraria's logo, especially on Terraria Forums?
Team Axe Pros:
I get tired of memes quickly and will probably want to chop down trees soon.
I'm a bit psychotic and it's hard for psychopaths to say no to axes, especially Lucy. (She says Team Axe.)
Team Something Else Pros:
Why just watch the world burn when you can do something, no matter how small, to add fuel to the fire?
Deal with it.
