I can thank runescape that grinding in any other game is not bad. Have so many friends over the years Complain about grinds. I take them to my runescape character, and show them what I did, how much exp I needed, and how long it took, even sat them down and let them do it... They stop crying... And cried for me.
If i remember correctly... Every skill was 1-99....and when you hit 50, that wasn't half way.... Half way was lvl92...becaise the exp from 1-92 was how much it took for 92-99... It was a. Terrifying run.
I got a few skills to 99. Lol.
Stopped playing back in March or so when Titanfall came out. 600m or something like that, around half of my skills at 99 (and 115 dungeoneering) Just watched anime while I grinde, good times. Started and hot all caught up with naruto right from the beginning last summer.
Oh, and one of my 99's was slayer :)
