Did you tried the battle commands ? (3 pages of them)
I'm asking this because not a lot of streamers aware or was using them.
Maybe those commands could help the AI to get better.
Unless you can actually set them to start off a certain way, its still fairly useless for the most part. I mostly use the get your ass back here and concentrate on this target commands. The other stuff like get out of your dolls etc since i dont have mine yet it doesnt really matter.
Im still trying to figure out the hate system, since its a bit odd how easy the enemy changes targets off of the loli tank. Wonder if the enemy AI specifically attacks the lowest lv members constantly on purpose.
Even when I tested it out myself, seemed a bit random with pulling hate and such. Its been bugging me for a while, since in MMOs I usually play a tank and if the game works the same way the damage output + taunting should generally keep the enemies on me. As only Elma can out damage me if she hits multiple crits after buffing herself up.
Due to this I took off the taunting abilities for now and just went for more damage and defensive buff for when in a bind. Since Im usually always fighting stuff a 5-8 levels higher than I am depending on the monster type.
Other small issue with the title is how the battle system works, it relies far too much on doing what the AI tells you to with the skills otherwise you will not be doing optimal damage. Big difference from the original Xenoblade. Not as big of a fan with this system as the previous game.
Everything else with the title is pretty great and most def one of the gems of 2015.
