The playstyle is up to you. Peek and shoot in tunnels, backstab, be that huge Atlas or Direwolf's sidekick, run with a pack of mediums and so on.
My preferred build for the Adder is one with four Clan SRM4 with Artemis and 6 tons of ammo as well as an extra 2 DHS. Modules are CSRM Cooldown and CSRM4 Range of course. Bring an Airstrike or Arty strike and you can start having some fun. If they mob me I just drop the whole airstrike on myself.

If you check the armor, I only placed two points in the back and put everything in the front. You're not going to run circles around anything with your speed so you are going to go in there and brawl. If they get behind you, the extra 2-4 armor isn't gonna save you anyway.

Your goal is to fire as much of your 600 rounds of SRMs as you can into the enemy's face and Airstrike/arty whenever you have the chance. Don't worry too much about dying 1v1 vs a Direwolf. Just make sure by the time he's done with you he has no CT armor left.

Just go buy your Adder, put all the armor to the front, put in the most painful weapons you can use without shutting down and charge in there and tear their faces off! Oh, and have fun doing it to.
