I have to ask and I will prob get jumped on by many, but why would you use defence in H&V. The only way the chain grows is for each person to keep hitting each other over and over again. You will get far more pts by let chains grow than you ever will by using defence. I just don't get it. You start a chain with some guy/girl you get to 4-5 and bam they throw up defence and kill the chain. Why????????
