its actually a terrible edge account. You have no chance against tanks and rune pures will be able to hit much higher than you, while also having great accuracy due to rune defenders. Not that accuracy matters when fighting 1 def anyways. You also will not be able to use vengeance. A max pure is pretty much for cosmetic value, they're terrible pkers at that level bracket.
That's 99 in every stat except 1 defence and 52 prayer, not 99, that is.
Anyways - for a zerk to be 95 combat, he'd be 70 attack 91 strength 45 defence 52 prayer 99 hp magic 99 range..
So, you'd be at an advantage. In addition, any real "range tanks" will be at a higher level than 95 if their defence is high. So don't worry about them too much.
I think the pure you named is a beast type of account if you learn how to PK with it properly, but as said above.. I don't know how well it'd do in edge solo.
I would steer clear from 99 attack, as you're just bringing yourself to a higher cb - you would hit hardly anything through a zerkers defence, and they would be always hitting against you. Think to yourself how baby maxed pures there are? Minimal. I suggest, take steps, try out obby mauller, g maul, d scim etc etc.
