anybody did the challenges yet? i finsihed them yesterday and i had to say one was hard as f|_|ck it was psi attack iirc.
tehy are definitely fun and teach you the counter system way better than anything else (learning by doing ;D )

it also unlocks a great avatar which i use now (look at my sig)

Thats a spectre (ghost like unit). I concidered doing the challenges only cause of that portrait, but i like my Zeratul for now.

I finished all challenges yesterday, Gold on 2, Silver on 3 or 4 rest I Bronzed.
It really is a good counter system teacher. I will probably do a few of them again. My goal was initially to get another easy portrait. Guess I'll have to try for the 10 1v1 wins next.

Finished all Gold challenges. Most of them weren't too bad; I needed the most help figuring out how to beat the 3 intermediate ones.

Psionic Assault must have taken me at least 10 tries, but when I realized you could use feedback on the Banshees that come towards the end and turned my High Templars into Archons earlier on, I finally nailed it with 227 kills.

The Bunker one was laughably easy compared to all of the others.
