yes you should
1.The player base is decent size more players will be joining very soon with their big marketing coming soon.
2.Long time value is mainly in pvp atm like the way you can crush everyone you see for a while then get owned by someone else forcing you to rethink and rebuild
3.yeah its fun and it doesn't get repetitive
