I've just started playing BFG recently, in a fairly active club that has a tournament happening in 3 weeks. I've been winning nearly all of my games, even against more experienced opponents, without a huge amount of tactical effort.
My fleet 1000pts (Forgeworld Tau, the forgeworld rules):
Custodian; Kor'el
2x Warden
2x Protector
4x Castellan
Many people at the club comment on my amount of 'ordnance spam' and get overwhelmed by my AC, though most of my opponents focus on guns rather than carriers. At the tournament we're looking to have about 5 chaos, 5 imperials, 2 necrons, 2 orks, 1 dark eldar and myself as the only Tau player. I don't want to come across as a powergamer at the tournament; is this fleet really that difficult to beat?
