Yeah, of course. Unless theire is a huge terrain advantage (such as a catapult to the sun nearby). But, Durge is reduced to goo, and every time he starts to reform, Jango shoots him a few times and Greivous chops him up. Then Jango and Greivous die of starvation, (or if in a terrain where ther is food, they die of old oage) and Durge comes back. However, I would hardly call that a "victory".
