I mean yeah its a standard Jack popping build.
Your flex points are in winning optimism integrity with leftovers in delegation. Out of those I feel optimism is by far the weakest as most only take the one point for quicker popping as the damage is nothing compared to what you can do with CM and ur kill skills. With those points (and the extra points in delegation) I personally go down the left tree with Take Their Freedom (for on demand self heal) and Jacks Cache (for infinite nades) while taking the one point in accountability, which is a pretty serviceable one point wonder as even at 5 stacks (pretty reasonable to expect in natural gameplay) its 5% FR and 10% Reload Speed which is basically a 6th point in Believe with the potential to be better than that, so I would spec into it regardless of your choice to go deeper into the hero tree or not.
Other than that its fine.
