Played in the monthly 1K at my local store today and got tabled by someone playing 4 riptides in turn 6. I ran two Knights, one 5 man tac squad with a librarian and another in a drop pod with a multimelta. My opponent put one riptide, with 6 haywire shots plus D3 strength 8 shots in front of a knight and another, same layout jumped 24" behind another the same knight. I could only Ion Shield one side and so I was wiped out in one round, then he did the same thing to another knight after i defeated a riptide in CC (after 2 rounds really bad rolling on my part and great 3+ invuls on his part). The troops were wiped out shortly after.
Other than CC how do Knights deal with that many haywire shots? I know nothing of Tau but I want to buy the codex just to figure out what the hell they can take.
I was stunned, especially after tabling a Necron player in turn 3 my first game.
Edit: Also I did not know that I can only snap shot my multimelta in the turn in arrives from a drop pod...
