Hey guys, i recently started the game and would like to gain some advice. I've read some post on cc-ing katie as my first unit, but i would like to know whats the best way to gain exp for her? Do i continue doing story quest and feed her with some iron units? or should i sell those iron units for gold? what level of bronze or iron units should i be feeding her and who should i work on next? Im sorry for the long post and appreciate that someone could enlighten me on this matter. Thank you!!
