I'm a Free to Play (F2P) player of Star Wars : Galaxy of Heroes.
I've been slowly grinding since March 2016 my character collection. Making mistakes, hazardous team composition and arena fails. Having read many sites, and made my own spreadsheets, I'll try to share some of my experience.

I used to be an avid droids player. But now the meta has changed, and my roster is getting large enough to switch between different teams.
Here's my profile for the curious !

Most pictures are from starwars.com (copyright, etc.) and are just there to lighten up the pages :)
