I been in recent discussions with friends in the game on how frustrating it is to earn certain one shot techs. You place them on an item/weapon and then get something better or new items/weapons are added to the game and you realize your tech is gone(ie....flaming weapon, Ice weapon, bone tipped). Most are earned through quests and are not repeatable.
How about adding blank augment crystals to the game. You tech the crystal giving the player the option to move it among different pieces of gear.
*I have just read Dakoren's post on the tech kits. This post can be added to his discussion.
