Aiming with Subs is relatively easy: Learn the hit pattern and aim where the bullets will hit. Aiming at the torso and a bit to the left or right might help.
As for Smash... watch Harakiris video about the hit pattern first. Knowing the hit pattern makes aiming easier. I find aiming at the side where the bullet hits first (upper left or right) and keeping at it the most reliable. Then you could take a look at this video from Juri which is a perfect demonstration of how to aim good.
lol dodging is my problem im trying to refrain from doing that so much cause i waste alot of time and sp doing that
Dodging with Rev to reposition yourself can help you kill people quicker. While it may look like it takes a lot of time from your perspective, it really doesn't. And unless you're playing with an active skill or you carry the ball you shouldn't worry too much about SP.
Since Revo depends a lot on positioning and movement you could experiment with that. Dodging, sidestepping without jumping, moving into your opponent, ... Just try what fits best in different situations and you'll probably improve.
