Wish they would allow Brackets in CCs (ability to create more spaces though). If they also allowed betting (sorry skill challenge lol), within that it, would be a nice option.
Just looking over at the current happy Brackets I see the grand total of 9 option's. 5 are free, two TL only for credits and 2 tierless for credits.
Any tiered one's even for Legend below TL probably, and certainly TM down, and it would be easy to see where all the Great Whites had gone from the worlds ocean's.
Brackets were a good idea, but hard to make them fit with the way this place operates. Thus, I don't think these are destined to be part of this game in any big way, unless they get them in a CC with a sensible WGT rake* when doing credit one's.
* And dear WGT that does not mean 20% plus ball costs if you need a clue where to start working down from quickly in a big way:)
