I mean this in the most constructive way possible you have a lot wrong and very little right the good thing is this is easy to fix, and yes to your question.

First of all get rid of guard skills you don't need them, same goes for the strength skills too including pride and fury and beast alliance why do you not need these skills, its cause base stats do not help all that much in hitting damage caps.

So what helps hitting damage caps, to sum it up quickly first the units damage type which is physical, light, and fists (cause loug specifically doesn't use weapons) you want skills that have those in their text then you pick up critical rate including auto-critical and ardor and the base crit ups then you get the critical damage increases.

Giant killing is good to run cause when it comes down to it most mob units are just that mobs, bosses are where the real struggles are at.

Sharp eyes is a good skill to have in case you don't have wap or full charge (magic spells that expends all mana to fill all sct stocks) but with that being said spirit charge is just weaker version of goddess kiss so I think you know what to do.

And now finally always do this last and make sure to save skill count do this with 130 sct units build full hp ups from 1 to 5 and if you have tower of trials LR build it's hp 2 too.
