Ambitious is a PERFECT trait for the Lionstone clan. The purpose isn’t to necessarily Ult FASTER. It’s to Ult AT THE RIGHT TIME. Both of these characters thrive on ulting exactly before other people ult. For the Male it’s before the enemy ults, for the Female it’s before your allies ult. I do not personally think that running Ambitious for the purpose of speeding up Ultimates is a good idea. When you have that goal in mind, Agile and Focused are much more valuable. I also believe that running Agile and Focused together is a great combo that leaves LITTLE space for the many other traits you’ll wish you had. All of those options, be they offensive or defensive, will certainly bring more value in most cases than Ambitious would. Of course, you should use whatever traits make you have the most fun! Even if they aren’t recommended here.
