What's with the 12 second timer? I guessed that this would be because you could just grab Homeguard after Recalling/reaching your fountain for insteant health/resource restoration and the movement speed buff (which I believe you retain if you have it up and then sell Homeguards or swap for a different enchantment, but I'm not sure) and then get a different enchantment, but I think 12 seconds is too long of a timer, clicking on the wrong enchantment means you have to wait that long just to get the one you wanted (it's already bad enough that you have to pay extra whereas with other items you can just hit the Undo button). Maybe this could be reduced to the timer between Elixir purchases, or maybe a little longer, but probably only double that at the most would be necessary. And speaking of paying extra, the buy-Homeguard-to-get-full-health-and-then-exchanging-it-for-a-different-enchantment thing isn't something that could really be abused because you'd have to pay 500g just to get your health full faster and then get the enchantment you want.

TL;DR: The 12 second timer between purchasing enchantments really isn't necessary as far as I can see.
