You can build full fury in about 5 second if you're solo. You can also potentially never reach full fury if you joined a team of only storm masterminds.
Building fury is relative to the team, your agro management skills, and your attack chain speed.
1. Getting hit builds fury.
2. Attacks the miss you build fury.
3. Hitting back builds fury.
The challenge, of course, is that on teams it can be, at times, difficult to build up fury from #1 and #2 depending on team make up because of others getting the aggro from the enemies. Brutes have powers that have a taunt affect build into them to make near by enemies attack you. You can add to this by taking a taunt, but I've found that is rarely necessary (the more that are attacking you, the quicker you build fury).
#1 is most easily obtained and sustained by putting brawl on auto and have it fire every time its up and combine it with other fast rechaging attacks and when fury is high, start unleashing the higher damaging (and longer recharging) attacks.

Fury seems extremely fun.
How fast can it be built? Solo? Team?
I understand that getting hit builds fury also.
If I was "leading" the team...taking the alpha...would fury be built up within the first group?
