Diffusal Rework

This.

OP as hell. 700 gold is nothing, it essentially means having infinite diffusal charges. You're essentially nerfing Omni/Warlock/Brood/Ursa/whatever by having everyone spamming diffusal purges every 2 seconds.

Right now it costs half of the price of the item to refill it so it's more like 2K gold.

Diffusal doesn't need a buff seriously.

Besides you're buffing heroes like Troll Warlord that deal a ton of damage but suck at disabling by giving them an ultra-cheap and spammy chasing item. I really don't think that's needed.

You don't need to replenish the charge by buying the recipe again.

3850 gold = 16 purge

It's 240 gold for a purge. Once you used them all up, you can sell the Diffusal Blade and buy it again, after that it will be:

3850/2 gold = 16 purge

Now it's 120 gold for a purge! How cheap is this! Not to mention the purge has only 8 seconds cooldown time. So the charge system is fine now and doesn't need any buffs.

I think the current diffusal system is fine. The change taking it out of the UAM category was a pretty solid buff and imo, helps ease the decision of getting one in certain match ups. The charges don't seem unbalanced for the price of the item either. The way I look at it is, if you're using up a charge, you should pretty much be putting yourself or your team in the position of netting a kill out of it (unless using it as a purge). All in all, I don't feel the item needs a rework.
