Nexus blitz is great, but I feel like the mini games are not really needed.
My thoughts about it are in the title, Nexus blitz is very fun but the mini games feel a bit out of place. They do their job of shaking things up and I understand that people defiantly enjoy them, however, I feel like they don't serve the purpose that I think riot is going for with them, that being a way to potentially rally a losing team, however in my experience with it, it just allows the enemy team to get an even larger lead. That being said it's day 1 of this game mode being out and they're in all likelihood going to fine tune it a bit better, just wanted to give my two cents about it.
