It's more important to get good support cards, (this comes with time) and add people with good cards and umas than it is to play a lot. I play 1 career a day, which takes 20 minutes, and I have multiple 9* and am top pvp class. When you first start playing you will play a lot more than 1 career and it will take longer because you'll actually be reading shit and learning what things do. Once you get your own 9* uma in the mix things just snowball.
