Revolution Slider was bundled with the theme we purchased from ThemeForest for our site, along with Visual Composer. I found that both of these tools were not receiving updates anywhere near the frequency via the bundle vs the individual licensing/download route. I ended up purchasing additional individual licenses so I could keep both plugins up-to-date. I've since taken the position that any premium plugins that are 'bundled' with a theme or other plugin will need to also be purchased separately in order to access more frequent updates and maintain the integrity/security of my WordPress installation.
