I am a level 180 battle mage with full starforced pensalir gear and chaos horntail equips with 120k range and i literally cant kill anything my level in reboot. I have no idea what to do..
I suggest taking advantage of events while you can as they have event rings which are pretty good stats. Also have you started your link skills? If not, I would start working on those as they help your damage, same with raising your legion.
I am doing a Reboot Solo-Progression journey as well. I can tell you, it is entirely possible to get to end game without being carried but it will take a lot of time. Having maxed nodes is definitely a improvement and highly good enough to solo CRA on your own before you even have CRA gear. You can also work on legion/link skills to boost your damage up even more.
