Your dislike of druids doesn't change my recommendation: 3 druids. If you're talking about 4-5 toons, then I wouldn't suggest druids, but 3 is pretty nice. 9 treants from a stealthed position, 3 starfalls, staggered typhoons... 3 druids is a force. 3 of anything else may not have enough synchronized firepower to truly be effective and overcome the many disadvantages to boxing. However, druids allow you to pick your battles which is huge.
