They are both easy to script. If people says it hard its because they dont know how to script and only manage to script by borrowing/editing other peoples code. In xeno its a tad harder to borrow code so they think its harder to script. My only problem with xeno is separate lua files which isnt a problem only an annoyance. Im hoping we get bult in scripts. one-liners are fine but they still dont work for scripts like attack area and soft boots changer. Once special areas are fixed I see xenobot as working well on knights and paladins. Im still not 100% happy using a mage with it. Maybe once I make a nice multi spell attack script ill change my mind.
Then your doing something wrong.
