On the other hand, and thats why I would never want to do it with my main account, its just boring. You don't need to attend matches, there is no excitement about the games you play as you will win almost every single one as long as you have your bonuses up.
that's true, but you can control the draw if you want.
If go with 10 good q + 4 low q, you can avoid the +1 LV and have also some interest games in Cup and CL higher rounds.
And of course it.'s very different when an experienced player start from the scratch than a noob.
