EA Jesse responded on this and I wouldn't hold my breath for any further changes. It's a mini game that expects attrition, multiple squads, to complete. P2P has nothing to do with it. Some of us have been playing this for 8 months now and having a filled out roster does make the difference. I don't auto through GW, I move nicely along until node 6 then get stuck for a bit, again at 8 or 9, then 11 and possibly 12. That's just me though. I know that the randomness of this game makes it a unique situation for everyone. I need to sacrifice a couple of squads and break my time up on finishing it. It doesn't take hours and hours, perhaps 45 - 50 minutes at most but I don't do it all at once either. So, is it really a problem or can we all just move past this? I personally think that GW and Raids are about all we have in this game that require some effort. The events are some times challenging as well, but it's hit or miss.
Also, I spent almost 2 months where I couldn't complete it, but I spent my 400 or 600 guild coins per day on character shards and in the end it paid off.
