Hate you? By the contrary, I'm thankful whenever people have constructive criticism, it always makes any project better. Now to the bullet points:

1) Whoops, didn't mean for the duration to stack. Reworking the tooltip to make clear they're only hit by the effect once. Will reduce the duration to a static  duration, just a bit more than  because he lacks her range and he's mainly a support.

2) Yes, Oil Slip is meant to be a powerful zone control that Benji can count with every time he decides to make a play. If I were to nerf the duration of the slippery oil to 5 seconds, that would force him to always making a play right after he uses the ability instead of giving him a window of opportunity. Remember, the oil drips behind him while his other basic abilities and Mist Cannon Upgrades work in front of him, which makes the application riskier than, since can apply all of his abilities frontwards.
 * That's my reasoning behind the duration/cooldown relation being the way it is, if you have another suggestion that maintains the ability's intent while reducing its oppressive potential I'll be more than happy to hear it.

3) Will change all costs except Hell Cycle. Yes, it's more expensive than it should be considering the stats it has, but that active can deal a lot of damage if executed right. It'd be rushed by almost all Benji players if it was as gold efficient as other upgrades.
