Traffic on hearthpwn is already down ~50%, You can tell by the number of posts that show up if you filter active threads to the last 24h. It used to be 4-7 pages but now it's just 3. I can only assume the posts all went to outofcards instead. After all, people who have no intention of swapping over have no reason to start posting less on hearthpwn
Yeah... Some if it's a little arcane but I wouldn't call it clunky.
I've switched to OoC for test-period but as Hearthpwn is ok again, I'm back because I like it more.
