I stopped playing RS a little before they introduced RS3 back in the day. I'm currently playing OSRS with only one account as a zerker build with mediocre stats and want to begin working on a maxed main for eog content such as RAIDS & ETC. I absolutely love zerker pking/briding so no matter the route I go I want to make sure that I keep a zerker build.
Would you guys suggest to just work on maxing out my zerker i currently have or create a new account and start from scratch?

The only advantages I can think of right now of just maxing my zerker is to continuously make money faster while training a new zerker and also perfecting the build by redoing quests in different orders/leveling/etc. I could grind on my Zerker leveling it while afkish training the new account for a zerker build.

What would you guys suggest?

Max my current zerker?
Make a new account and max that?

Make a new account for a main. No point in ruining your current one.

zerkers can do most stuff, just stay 45 def and level that account.

There's nothing a zerker can't do, less efficiently than a main but yeah.

tldr but main>

Main
