"My problem is that credits should be used for packs
only." As sb. not associated with the company... Why? Let's take Magic: You pay for cards, right, but also for protective sleeves, life counters, novels... a lot of extra stuff, in that case mostly phyiscal but clearly connected to the game.
No, I am not overly thrilled by this since I feel slightly forced to spend credits there in order to reach my goal (all mission points!). That's surely new and the first time one goal is simply barred without spending credits there.
Then again, it is not a big thing in my opinion. I played years without buying Credits; I finally bought credits... if I break it down, I payed approx 3 cents per game (not sure on the exact number of Credits I _bought_)... which is quite fair, imo - I cannot really do price/time.
One can easily look at it like not being usually free... it usually IS NOT THERE
. Still, I see where you come from and as I said I am not overly thrilled and a little worried - especially since it will be comparetively short and one off but "must have" if your playing focusses on mission completion - and there is no entry fee for ELO
or tournaments after all. It's a bit... strange.
Bottomline: On the "ambivalent" side but with leanings to "still ok" rather than shady cashgrab.
