well get rid of the protector, get another epic/ if incredible lucky legendary hp module, let go of the legacy regen module, and put another heat engine.
For modules, replace the legacy with either new modules, once you upgrade them they surpass the legacy by around 50%.
Let go of one of the side wepons, and put another last words. Also look for a histeria(electric top wepon), or grim cobra.
And start upgrading evrything, torso first, then legs, then wepons, and last the modules.
Take them all to mythical, and start having fun.
It is a decent base on wich you can build.
If you need more help, ask away.
