Same here, got a lew laptop.. Now this S**t

My intentions is to be a tank, but tbh i also dont mind do some dps. only the thing is i got tank gear.. im a jedi guardian.. and i have no idee what to do now to get some gear or what gear is needed to tank for hardmodes. anyone got any tips for jedi guardian what to do ? Shall i go tank or dps. What gear and stats i realy need to even think about doing something in pve. Any tips on ''melee''-tanks. What flashpoints i shall hit first to learn.
