All I see about this complaining is a bunch of titan-or-above level players shouting: "HEY UR STAFF, GIVE US BACK OUR NOOBS SO WE CAN STOMP ON THEM AND FEEL GOOD PLAYERS AGAIN"
I like this new mode, gives you the chance to get through "win X fights by K.O." without the chance of your opponent leaving the battle when the screw up. Also, you see Kate playing with clans you don't see often (out of Ld weeks).
Gives new players the chance of trying and get new options for decks by giving them common cards, so they don't have to make their way through UR only with the basic deck against fully developed (and surely more expensive) decks..
And giving away common cards don't seems too bad for me: some artificially inflated prices for common cards will have to go down, yet I don't see every card price crashing and burn.
By the way...
When I started in Urban Rivals, I tried in classic mode to get used to the gameplay, and all I remember was noobs like me, and a bunch of 90 level players with Ambre
decks, waiting for those noobs. This as all the time, and not always the same people. They weren't on the "challenging" modes (big prizes). This hasn't changed yet.
I think this will help this, by leaving the championship room for those who fell prepared to face a human opponent and the popular decks and clans they use.
In the end, I see more pros than cons (for some players).
So go now, and have fun!
