A good supporter always makes a very big difference
Get one of your buds to q with you together and try out a combination that could win the laning phase nicely and to be able to help the other lanes later on , that's usually the best thing to do if you want a duo top or bot. You'd at least have a person trustful to hear you out what to do etc.
When it comes to stacking, there is also the trick that, if you're good with basic micro you could double stack with the help of Helm of the Dominator item, you can control a creep, bring it to a jungle creep spawn, pull them in one spot with the creep in your control and the other spot with your hero and you've 2x stacked, that also works nicely in case you don't seem to have a nice supporter on the team or any at all for that matter. Also, as a recommendation from my own experience when you are in jungle and there isn't a supporter on the team and people are bitching about no wards constantly, if you do have the gold for it, get some wards yourself and place them in the jungle, the fact that 150 g spent on an area to see if they're coming for you, will save you a lot instead of no vision and being paranoid and you most likely will end up getting ganked and losing precious money + exp time.
