I would like to request that magi items and false life items maintain the % value of the appropriate stat when you equip them.
Currently, if you have 200 / 200 hp and put on a greater false life item, you'll then have 200 / 230 hp. However, I feel it would be more beneficial if you put it on and went to 230 / 230 hp. Now, before you state that this will be abused as a means to "heal for free," I stated it should maintain the % value. 200 / 200 is 100%, so equipping it would take you to 230 / 230, again 100%.
If, however, you were at 20 / 200 or 10%, then equipping the greater false life item would put you at 23 / 230. This would allow players who are already juggling a lot of gear a bit of leniency if they forget to equip their hp / sp item before resting at a shrine. As long as they equip it before they begin taking damage or casting spells, they will still be able to receive the full benefit.
Keeping it a % instead of a flat value will remove the risk of people using it as a "free heal" (or "free mnemonic") exploit, while adding a bit of user-friendliness into the current situation.
