If 343 wants Halo 5 to be the next big eSports title they need to make Halo 5 competitive out of the box. According to Frank O’Connor on the Giant Bomb E3 panel, 343 aims to take Halo 5 back to its roots and make the game more competitive.
Simply having a game that can be competitive isn’t enough though. For a game to be a successful eSports title it must also have a large spectator following that may not be interested in competing. What this means is that the game should be competitive without needing to make adjustments to the movement speed, power up placement, starting weapons, etc.
