Limit to # of Event Rules

I'm not aware of any known limit on the number of Event Rules that can be created. However, it is best practice to keep these rules to a minimum. We recommend having one rule per event on the page that you'd like to track. You can then use the logic within the rule to fire the needed tags.

Each rule created increases the size of your library. Having a big enough library could have a negative impact on your page load.
