Also i totally agree with L8Rdays. And i approve his words since i dont have most of LDs and i'm really frustrated i have no possibility to obtain that sweet cards. Well, i'm not such a new of a player and i won't leave UR on this occasion but it still feels like a spit in the face.
Don't get me wrong, i understand that staff wants to change LDs from average cards obtained from grinding missions to cool cards won in challenging arcade. But ! Since you haven't implement some stable source of obtaining that cards(i.e. more arcade seasons) why dont you keep Ld missions for the time being? That lacuna we have now is really uncalled for and easily avoidable.
Personally, I'm having a hard time keeping up with current (new blood) missions (just barely finished those stupid RB missions in ELO) so I'm kinda glad there are no new Ld missions coming out every other week. If they're going to keep doing Rb missions (they haven't released any lately,so who knows), I'm okay with Ld missions being gone. Plus with Duel gone my ability to grind missions has decreased dramatically.
I'm all for changing the stats of the Ld cards, but what about the Rebirth cards? I mean, if you're going to change the art style of some of the old cards and then call them 'Rebirth', shouldn't they get better stats and some cool abilities to go with them?
