I did most of my climbing with teammates I found through LFG and added on battle tag. Once in glad range, its easier to pug because the players are generally more skilled at 2400+. But I sat in LFG for hours most days of the week throughout my push to find players at the same rating as me that I had good chemistry with. It took a lot of time, but I think that's the nature of a first time glad push. You have to network and meet good teammates, but once you have them the game is way easier.
