Truthfully even if they patch the game that majority of the fixes will be done in the xmls for the problems you are observing so your current game is going too still be flawed unfortunately. Now I love the enchanting in the game because it can enhance the items especially the splintered staffs that add movement or the Midnight stone for 10% experience increase, these may seem negligable but they can add up fast if you have them on multiple items a 100% increase in experience is nice even if it is spread over multiple items, or even 10 more moves equipable on any unit. The coolest is demon horns for +1 mana per kill, if you can put 10 of them on a suit of gear, that is 10 mana for each kill the equipped unit does. In a game where getting mana is like squeezing blood from a stone; killing 6 enemies with +10 mana from each kill, 60 mana from a fight, now you can actually afford to enchant or cast spells in combat finally.
Ofcourse Tinkers can have 3 enchantment slots per item so they totally rock(mine have 4, and the other sovereigns have 2 slots, because I love the enchant mechanic). The flawed part of enchanting is only in the spellbook enchants, and since you only get to use those once each maximum if you can get them( have not seen any way you can the the spellbooks as loot and they affect your spell selections), it would not affect you much.
I personally believe you should at least be able to find spellbooks as treasure(and that is not hard to mod in the xml, just tedious because of how restricted they made the loot in the game). You will loot a ton of plate gear and shadow swords, but you have to loot leather then make leather equipment, or get iron to make chain stuff, also rare can random enchanted items seem to be things of the past you get recipes then you have to make them yourself if you can get the ingredients. The MAKERS could do a tone of fixing just from reading through the xmls and adding descriptions to items and abilities, this would allow them to make sure the description and abilities match, and that the scales are valid, I mean saying you give an item 50% chance to maul, when it actually give .5% ie no real chance at all is just careless.
Now I have a question for you do you believe Xii should be able to only teleport to friendly territory or should they be able too get to pretty much any territory you can see?
