since a week ago I've noticed that the monsters in this area are dealing alot more damage and I can't even clear a tree before it dissapear. I notice it and I need to ask because I can't be hallucinating I went from level 61 to 62 there so I used to be able to grind there solo. I was guardian. and had 293 dp. I am dying really fast now. did they changed something I didn't see in the patch note?

Are you grinding at night time? Monsters hit harder at night by a lot.  

Are you remembering food buff (siimple cron meal), villa buff (body enhancement), church buff (roll 8 DR), beast's draught? 

Did you have a perilla's star or other alchemy stone that improved your damage resistance? Is it expired or out of juice now?  

You double check your gear is all good - like you didn't swap out something good for something bad by mistake?

You also said "I was guardian" well what are you now? different classes have easier/harder time dpending on your playstyle and your gear too. 

I used to grind anytime that didn't affected my grinding there. I don't have the tent and only used the oasis food. But it was enough. I sure to clear the complete round of voraros sometimes including the big 🌲. That spawns them. I had nesser gear now using nachillan for the monster damage reduction which does nothing in my opinion. 293dp was good enough but not anymore I switch to warrior since nova kinda weak. And still not helping out of the 3 guardian was the strongest. I used the the normal distruction stone but I guess they added better free gear so they changing areas to keep players on the lower areas untill they pay their way up.
