I love playing Tau, but I absolutely abhor a few things about the faction. The main thing is the Burst cannons. They're ridiculous. My second, although lesser, pet peeve is the XV25 stealth suits. I love how they play on the table, but I have issues with how they actually look. Something about the rounded carapace just doesn't look so good to me. XV15 stealth suits, however, look fantastic, and miniguns that look like, with some luck, they could hit the broad side of a barn are something I definitely want to invest in.
As it happens, I have found both of these online, the XV15 here at
