Personally i like the battle mechanics as of how it works now. It allows room for job customization although i do agree that it still need some fixes here and there. As ff14 is still a new game, many people are trying to find the perfect build for their favourite job. Take for example, i prefer lancer above the other jobs and being able to equip abilities from jobs such as thm or con enable me to be able to solo things which will otherwise be impossible as everyone know that lancer is paper-thin and this point alone is a important factor as it adds more depth to my game ^^
