Farming sponsor zone with any aoe weapon (thumper preferable)
Cake Boss (The cape can be used to hit the capped damage, while its still there)
Sires although not everybodies favourite, is a great money maker.
In all honesty i personally dont see a problem with the current ownercape, althought understand the concerns. But adding more bosses to be one hit by the cape would somewhat decrease the value of the executive cape/zone.
If there are any other alternatives be sure to post them in the suggestions, either using the link Bowl provided, or on discord. Be interested to see what people come up with
