The game ain't a P2W one like most players were complaining about, and based on the screenshot that you have, you rushed your Main Quest without giving time to increase your Knowledge and other things which would've made your Character probably reach 20k CP.
Things you've missed and might want to give attention
- Hadum Knowledge
- Boss Knowledge
- Rift Stone
- Runes(do your Great Desert)
- Enchantment for your Gears
- Enhancement(Aim for atleast PEN(V) Resonance) in the meantime)
- Glyphs
- Rift Totem +6(This should be easy considering the events)
- Upgrading your Mystical Outfits
There are plenty of things where you can gain Combat Powers with your current state. I strongly recommend you know how to play, before you say its a P2W one.
