I think aggressive batting is good for test cricket. It has produced more results than draws which was killing test cricket 10-15 years ago. Guys like Sehwag, Warner etc have changed it and its good for test cricket. Answer to the Question on Warner being a test cricketer or not should not be based on just his scoring rate. He lasted almost a full day, was dfensive when needed and attacked bad deliveries. That's was test cricket is all about - score and bat long. These guys have done it on good seaming pitches as well. I think this is good for test cricket. There were other guys who got out cheaply, which makes Warner's innings even more Creditworthy.
