Know that guardian that always show up when you're doing a public event by yourself and help with that chunk of damage that you wouldn't be able to finish by yourself ?
That is you on this tier. May not look like a big sacrifice to you but is a great help on my side.

You know your ways around, you know you can help and you're willing to.

The price may sound a little awkward, but if you keep looking at the next tiers and do some math you will probably understand it.
