Seriously Vaclav, unless you are homeless, just fucking buy Naxx. Or borrow a penny from the 50,000 relatives that you always use as sources.
I probably will, but I'm playing like 9 video games right now (and don't even touch them many days with 2-3 boardgaming days a week most of the time now...) - I just knock out my dailies and the occasional arena as it stands right now - I flutter around Rank 8 and I'm fine with that. But yea, it's something we might be tossing in the budget for the end of the month x2 (wife will insist on getting it too when I do) - but the whole "you can get it F2P" is always a motivation for me to keep hoarding gold/etc.
Remember I'll spend a week or two sometimes to get a last trophy for a PS4 game because of being persistent - carrots to motivate further play aren't necessarily a bad thing - I'm mixed on buying Naxx simply because if I get basically done (which I'm getting close to - was already "done" besides shitty Legends and Golds which I don't care to fill out either before Naxx - and GvG I need two more Legends that I feel will have any value ever, and got 1400ish dust right now, so almost done there), I think I might just end up going on vacation from the game again since I'm not motivated to do much besides capping gold for the next xpac after that and the last GvG legends.
Paying $40 to just go on break for a few months again doesn't make much sense, might as well draw it out and give me an excuse to continue playing. Affording it's a joke - but wasting money just to speed up taking a break from it seems silly.
But even while saying it's silly, I'll probably do it - but honestly it'll remove a carrot that's keeping me playing. (Also I play with my wife's recent BF's kid at times - and he's completely F2P - so would be unfair to subject him to, would have to play down for him now that I think about it too... =/)
Column: I haven't watched the streams enough, but isn't near Legend gain a star on win, lose a star on loss (or worse...)? You'd need above 50% to make up for that unless you're just relying on winstreak bonuses to actually progress - and that seems a terribly slow way to go - 60% or so is where the math at least seems plausible to me.
And I do use many nonstandard Priest cards that really help with the MechMage matches - Shadowboxer is a wonderful thing that screws with their math for example since it can solo MW's easily and give extra pressure on others unless they super spam, but still useful after a super spam since they can help pick off the survivors with 1-2 HP. Etc. Only card in MechMage that gives me trouble (besides the few that run Unstable and get super lucky of course, but that's just random chance - and with clones and enough on the board to kill many things it's sometimes something I actually take advantage of anyhow) is the 5/4 goblin dude, but that's just because the RNG always seems to go absolutely the worst it could for him every time - and he's got a large body in comparison.
