I'm so happy with this patch.. Earth Spirit abilities reworked, hopefully he wont be the OP piece of shit he's been since release now. Necrobooks slightly nerfed, Timbersaw slightly nerfed, Slarks pounce slightly nerfed (altho shadowdance 5s less CD) and Brood nerfed.
Gonna quote myself from a week ago and feel good about myself

I've just about had it with furions, timbersaws and earth spirits 
Furion is just gay, timbersaw is somewhat op, earth spirit is just plain broken. Slarks broken too. Icefrog needs to step up his balancing
