So I gave Block n Load a try (now that it's FTP) and it's fun, you get to build up defenses and then attack/defend points
It combines the best of MOBAs, Minecraft and FPS games together
All that with a goofy cast of characters :)
I'll give it a try!
It's a lot of fun and the rounds are a good length (not too long not too short)
Each hero is capable of both attack/ defense so it's up to you to decide where your strengths are with that character to serve the team
Of course team variety is important too
