A shit ton of units that got buffed in that patch now show up.
-1 Food and Taunt buff kinda does wonders, they're just massive walls to overcome and the only unit type that counters them (Big Melees like Tauren / Knights) are rarely built, let alone in great numbers.
Yes and no.
Pit Lord is basically a DotA Carry now, you laugh at him at first, but once he hits 5 and has enough Dps items, he just cleaves your army.
Grubby tried Pit Lord in his stream post buff a few times alongside Unholy Frenzy, might not be a Meta Strat, but holy shit that cleave damage.
