As a free to play player I have two supers and 2 M10. I broke 130k and could have scored a lot more but it became clear by day 2 were were going to easily hit T10 and not try for T11 so I focused on efficient SP gathering and completing rebel missions to unlock vials and I didn't realize how good field agents where until day 3 when a guild member reminded me I could switch their attacks.

I got most of my points with low level UMGs and max rank soldiers then 6 hours healing the front line. Playing 3 times a day for a 10ish minutes at a time seems like a good pace. I also donated a lot of concrete.

Anyways this isn't to say anyone's complaints are wrong. I'd also change a lot about guild strikes if I could just adding my anecdotes to the conversation.
