Perhaps it was how you described it, but unlike RuneScape game seems like it was especially designed to discourage years of dumb grinding that literally ruins lives in games like RuneScape or WoW. Just appears to be a basic buzz kill the way XP works long-term. EQ was far worse than WoW together with grinding, as well as moreso than RS. It is the exact opposite. RS gold game ended up putting the capacity to purchase Pizza Hut straight into RuneScape game, this was like ~2004. The entire culture around RuneScape game puts the South Park WoW event to shame. RS is a whole lot easier going in contrast.
Runescape for me is always a perennial cycle of"ill manage to have much fun once I complete this 200 hour grind of X" Get to"x", find it super underwhelming and stop for 3 months. The two back in the day and now I put a more reasonable aim, hit on it, switch to something else for a while, helps with burnout. I have not logged in for a few days and just powered back up to 100 battle. Did the exact same thing when I hit at 88 fletching and came back. Once I get 70 all and max quests that I will end up playing very sparingly, or quitting though. However, for a lot of RuneScape game there is enough going on until you reach higher degrees.
I thought the grind to 65 att along with def, then str (somehow believed I had def instead of str to get in the warrior guild) was a long mill and I was only going from 60. I grinded out 70s and realized my grind was tame. Next got 80s and felt that the 70 grind was tame. I have 81/84/79 89 range 80 mage and 70 prayer and don't really remember the grinds. For me the grind that is current feels like the preceding one. I am already half way to 91 and only got 90 farming. Some cheap RS gold skills I really do hate though. Fletching is simply 57 I think and I train it so my Tears of Guthix visit RC. I also hate thieving. RC is bad and agility is ok.
I think that is normal man. I mean nothing AMAZING like real life accomplishments, although that I get a sense of achievement and I love it, it's a video game after all! If you are expecting some big feeling of achievement I believe that you are going to always be disappointed, or Runescape is creeping up and maybe getting too big a part of your life (I've been there when I was younger throughout rs2). I believe that the thing that can get dangerous is that people begin to get most of their feeling of accomplishment during RuneScape game, and unlike real life, If you set the time in you WILL accomplish your goal no matter what. However, as you have seen, it does not mean anything and it isn't satisfying like life.
