Quoted from Rob_G:
In stark contrast, the multipliers on GB are extremely difficult to get going, especially the 6x. I don't even think 6x is normally achievable by anyone but elite players or if you luck out and get them lit from a tobin award. In over 200 games I don't think I've ever had 6x (2x and 3x) going - oh wait, maybe once I did and drained right away.
Are you aware you can select the middle lane on the plunge and award yourself 2x and 3x? You don't have to be an elite player to achieve that IMO
