I am currently working on my second build so i am fairly new to the game. I wanted to play as a kind of melee/rifle user that focuses on mid to close range combat. Can you give me any tips on which weapons i should use, where i should put my stats and if i should use psionics?
You won't have enough stat points to have three stats be good enough to carry you through the game. You can get enormous benefit from psi with only 3 Will and 80 skill points. As long as you don't mind the health pool reduction (and it's not really all that bad) then sure, go ahead and play around with psi. Put 55 real points into Temporal Manipulation and 25 real points into Psychokinesis. That'll get you psi haste, psi slow, the cooldown reduction ability, and the force field. That's a huge set of additional capability to be toting around. Sure, you won't be landing any hits of any significance with your psi, but what you'll be able to do is use psi to make your rifle and melee all the more deadly. Plus, very early on when it's difficult to afford ammo, even your weak Temporal Distortion will be enough to get you zero-cost kills on stuff, and it'll let you handle turrets without blowing through your ammo reserves.
If you've still got skill points to spare in your build, you could get additional use with further investment, but 80 points gets you some really huge advantages.
