I have only played it in dailies. I'll be sure and try and snipe you with it soon, should be fun. Not tons of great beasts in FS or it would be cra. Makes me want to move away from the beast synergy and just go with a mixed meta of stealthtrap, KB and stuff. Besides the straight up OP damage the spells bring, it also allows you to safely overstuff your deck with ranged champs knowing you can drop 30-80 dmg on anything someone deploys that's strong against range.
Pygmies can take brutal advantage of soften/sunder/battlemaster/boost beast/mark and even drive and warcry. It gives champions like concealer or ironfist agent to solo champions for the same price of blink.
