This is why I did not bother with brawlers guild.
Not only do you have to fork over lots of gold or beg for an invite but you also don't get any rewards worth while from it.
Useless solo content.
Don't forget having to wait 10 minutes in between fights and being useless if you're a healer.
Got my brawler's invite for 1.5k gold yesterday from BMAH (quite funny competing with an alliance pushing the price up to 10k, letting them have it for 10k, then buying the next one for 1.5k).
1.5k gold takes, what, an hour to get? Hardly "lots of gold". Just a question of buying smart from BMAH.
10 mins in between fights? I was doing this at 11pm last night (not an unearthly time in the morning) and it was more like 3 to 4 mins between fights. Plus it was quite fun watching in between my fights to see some of the content I would be facing later.
Useless if you're a healer? Name one healing class that doesn't have a viable DPS offspec?
I don't think the rewards for this should be powerful like PVE Normal/heroic tokens. However, I think some nice cutsy/ashetic rewards would be cool like a unique piece of transmog gear etc.
