Why is Octane still so bad?

@Bean2kay9 While I agree Octane is generally useless to the team as his abilities do not really help I disagree his stim doesnt do anything. If used properly a good player strafes like crazy with the stim.

I have seen this suggested before but I think he needs a rework. His jump pad should become a tactical that only he can use. This would be similar to loba or path or wraith for escapability. His ultimate should be stim for his whole team. It could be a totem he drops that they touch to get like revenant or something that just happen if you are close.
