here's the thing iv read many threads but i need a direct opinion

I just started Delta-7 and its been really hard. I was wondering if you guys had any pointers or tips for me. Even just for that campaign.

My skill set is:

0-1-3-4
2-0-2-3
0-0-0-0

any pointers on that? Any combos or even things I should change.
Iv tried using the grav well, nutron stomp, grav slam and then singularity, but it doesnt work that well in Delta-7

PLZ add me at Agentsk any help would be great
