Jaurim's Fist needs a buff. There's no denying it.
Jaurim's fist is the AD equivalent of Seeker's Armguard. A pitifully plain and gold inefficient item that scales with minions killed. It is meant to be somewhat viable to rush it, kill minions, and sit on it for a little while like Armguard.
Problem is, the gold efficiency is completely out of whack. Compare it to Armguard and it becomes painfully obvious. ** Juarim's Fist**: **77% ** gold efficiency on purchase. 110% gold efficiency at 30 stacks. Gold efficient at 21 stacks.
Seeker's Armguard: 86% gold efficiency on purchase. 138% gold efficiency at 30 stacks. Gold efficient at 11 stacks.
When building one of the 4 items Juarim's fist builds into, you should be able to choose if you want more upfront stats, or better gold efficiency in the long run (before the bonus is reset when combined into a full item). You can't really do that since most items aside from tiamat (which has an extremely powerful passive and active) are just as gold efficient as a 21+ stacks Juarim's Fist. Right now there's a simple pattern. You always buy Juarim's Fist right before upgrading the item and try to have it in your inventory for as little time as possible.
Just make it slightly more gold efficient. Maybe not as gold efficient as Seeker's Armguard since there's a bigger tradeoff for rushing AR than AD/HP which is built by 90% of bruisers, but it needs to be better than the piece of shit it is right now.
