I am Leveling with a friend, currently we are 30. He is a Sniper and I am a healing spec operative. I use my comp as a tank, So far we have had no trouble doing any quests even heroic 4s. But im finding as healer spec, when i do the agent story line quests solo that im starting to struggle with dps. So if you use a healing spec, i would use a damage companion.

server is ofline i cant log on . but my friend behind me is playing im watching him

so ya get a pug rating like ranked pvp, but for random groups and as ya win it goes up. so ya get matched with simler pug rating players. that way your more likly to get matched with simler experiance or sensible players as they would have had to do multiple flashpoints and know the tactics ect. not sure if this would be viable but it seems a good idea to me.
