[Could I solo Bandos?]

Well, im Fairly good stats (use sig if you want to see) And iv gotten 2 kills in one trip (both using sgs\ags\dfs)

 

so either isuck, or its harder then you think

 

[Quickest way to maxed melee?]

Well, im new to fourms, but iv been in runescape for a while, and i myself have 99 strength, i hit fairly high with the right gear (about 50's with whip + str gear + piety + pots) = quite a lot of xp per hit, so i reccommend

 

Strength > Attack > hp > defence
