Nexus Blitz is too fast (including suggestion)

In one nexus blitz match, I go through at most 2 events. It's too fast and too boring. I feel nexus blitz should surround the idea of these events.

My suggestion is to make victory achievable by winning events.

1. Set an odd number of events, like 7 or 9.
2. Give each nexus 4 hit health, like a control ward.
3. Block it off from player access or make the nexus immune to player damage.
4. Each event win takes down the nexus HP by 1. In other words, it's a best of # event win to win the game. If it's 7, it's best of 4. If it's 9, it's best of 5, etc.
