Yea, not gonna take you years lol. I have the same goal and sometime this week it will finally be finished(>500k to 99 slay). Took me about 2 years(with a year hiatus). So all in all you could be done in 2010.
Mike ftw
I've known you for many years and you've achieved quite a great deal in that time. I have not a doubt in my mind that you'll be able to aspire to whatever you want to be
A lot of people give up on their long 99 goals since they don't get any satisfaction for level 90, 91, 92, etc. but with Slayer you get to achieve 99 Attack, Strength, Defence, etc on the way! Makes you feel like you're actually progressing - for that reason you WILL do it!
