i think at this point you have to start micro'ing yourself, this game takes alot of the stress away, but if you remove much else it might as well be a sci fi movie, you can't expect the devs to code abilities and then set priorities as well as situation and health related triggers, if you're attacking a starbase what are you doing, do you jump in the grav well, set attack and sit back and watch? Guaranteed there are other ships you could use abilities on that would reduce your losses or increase chance of victory.
With the titan you dont want that kinda think on auto cast anyway, wait for an opportune moment, such as attacking an advent sb when it uses meteors?
The hull restore when you're at 60% rather than 80 to reduce chance of overlapping, ofc its all situational..
There are some times when i think dam i wish my iconus used shields at the right time, but then i thought.. id rather be in control, like with repulsors since it is so useful when you take control yourself, you get a better feel for the fight and will always come out on top of someone relying on autocast!
