Valve needs to add stuff we can buy once we're full build. I hit my full build with just 46k souls
>>538168292 and I'm just stuck sitting there with 10k souls in my pocket not doing anything. Like how Dota has Moon Shard. Maybe an upgrade for utility items like Fleetfoot and Split Shot that make them permanently part of your hero and freeing up an item slot like the Aghs Blessing. Obviously things you only buy when you're full build cause obviously it just exists to free up a slot or to give a bit of extra stats.
