Why do you punish players for building a team?

One month is still VERY early game. Yes, multiple teams will help you, but that is your ultimate goal anyway, and you don't need to spend to do it.

The other thing is what mods you have. Make sure you have the right sets and primaries, certainly, but also having really good speed secondaries will help immensely. It does take some time to get up a nice collection of those.

The difficulty of GW does cap around level 85, so eventually you'll start to find it incredibly easy.
