I just got Mr 17 and unlocked Archon Hunts, but it is so hard for me that I got unmotivated and honestly have no idea what I should do next.
As soon as I found a favorite gun (that would be Fulmin), I spent some plat to make a good build for it and after 7 forma I honestly was really happy with the result, it was helping me through a lot of content (except Profit Taker) and I was really enjoying it... Until I reached Archon hunts.
The mobs in Archon hunts barely take damage from my Fulmin and also do a lot of damage to my frames to the point that right now is impossible for me to solo it, and I don't like being carried every week because it feels like I'm leeching. So please help me what should I do next? I'm on my way to unlock Steel Path but I got my ass kicked so hard I'm not even confident enough to tackle SP without being carried again.
You might want to look into some armor strip if you want to do damage to the grineer more quickly. Unairu operator, Saryn, Mag, Necros, Hildryn, Ember, Vauban, Xaku are some that can do it without augments. If you have access to helminth you can put something like Necros terrify on anybody and you're good to go.
For survivability, you can use certain frames or look into shield gating(augur mods and/or brief respite). What can also help quite a bit is jumping and rolling around - makes it so fewer bullets hit you.
