Nexus Blitz - King of the Hill idea
For Nexus Blitz, if King of the Hill ends up as an event, make the spot spawn at Rift or the buff above it. This way, it's in the middle of the map and less favored to your team/enemy team.
The few games I've played, the spot has spawned closer to the enemy team jungle tower. Which wouldn't be a problem if the enemy didn't get it because they respawned and were able to kill the few people trying to get it that were still alive. By putting it in the middle, it's on more even ground as all players can reach it around the same time, rather than one team losing it because the other team was able to get to it quicker than they could.
