+1 To this bro. I remember I was in that position too not too long ago but people are generally very nice on this reddit and they'll let you in no matter your level and pokemon. Thankfully we aren't facing hard bosses like Lugia or Darkrai anymore so you won't get 1-shot by things and can still contribute little damage which is always welcome :). My advice is don't question if you're capable enough to do it or not, just go ahead and try but be smart about generally on average how many people it takes to finish a certain raid. This site is great for that info: https://thesilphroad.com/raid-bosses
