Those ideas are pretty nice!
What about a Battle Mode, where teams of 6 players each face off in the arena? Maybe you could pick classes, like Warrior (Arrow Block 1, Hammer), Rogue (Jetpack 1, Energy Capacity 2), Ranger (Bow, Energy 2, Arrow 1)!
That would be pretty cool. Although, it may not fit in with Clone Drone's gameplay style.
I agree. it feels a little.... minecraft servery
