I see the game guardian a lot and have reported it multiple times. Not sure if this is some sort of broadcast hack or paid service you can get or what but it's total BS.
That's called cheating... We've seen a couple of bots during our CvC matches and the "person" will score over a million per turn so they could score 10million easy on one round of CvC.
the folks in my club that are VIP were able to get theirs granted early on so I assume it's transferable. They just had to prove who they were from 17.
Same for my club. Tier 6 used to be something we would get in an hour or two or before Saturday on weekend events. Now we aren't even getting Tier 5 most of the time.
I got to gold before I realized what a mistake it was and I've hung out in the playoffs for Gold lvl 6 for months and I don't plan on going any farther.
Some folks will play both, it really depends on how much you have in your team and how much time you have on your hands. I played both for the first month then went to just 2018.
