Nexus Blitz would be better if..
When it gets to 18 minutes, instead of just having the nexus go to mid, but all 5 towers too. I just lost a game when the enemy team didnt have a single obj. But the nexus stood up as we we almost had it at 0%. They all spawned, late game darius. Aced us after just finishing a team fight and won the game because they didnt have to do a single obj.
So all we have to do is turtle for 18 mins and objs dont matter. Great game mode you got there, riot.
