If it's something that you enjoy (obviously) and you aren't trying to rehab an injury I say go for it.
I play lacrosse (and would love to play rugby as well) and it consists of some of the same Pros, albeit with not as many heavy lifts and it's 4, 15 min quarters. I am employed as a shutdown defense-man because I hit very hard and can bring down an entire lane (usually the center) if they need me to. It requires sudden bursts of speed, agility and coordination.
Both primalrob and Winterbike make valid points, it's more akin to playing rather than chronic cardio but you do have to think about the impact of the hits.

Reason: Read MightyAl's post in other thread - he had a reason for saying it.
People too weak to follow their own dreams will always try to discourage others.
