I'l log another vote for I'm not sure why you need the extra click.
I did notice it that it only counts if you click on the card.
Unless it has something to do with click counts though on the website and traffic generated for ad revenues, I prefer the one click. It does help to get the bottom advertising banners seen better though.
SEPARATE ASIDE < me thinking out loud> :
The other thing I'll share, and I'm not 100% set in my feelings about it, but part of me seems a bit irked about the whole thing. It seems a bit gimmicky to me. I know I've been proud of the gold I've "earned" thru completing quests and challenges and now to just have to click button a couple of times, and I've gotten the same amount of gold, and somehow that seems off putting.
If it's for the betterment of the site, and to help you pay for hosting such a fun platform, I'll accept that, and be glad that you can keep providing the service you do, but if it's just there to give an easy path, well then, I'm not as happy about it.
If it leads to something more interesting down the road, I'm all for it.
So that's my 2 cents as they say here in America. I hope I haven't offended anyone, and have shared in a respectful manner.
