If you mean deep wilderness it's not nearly as bad as people make it out to be, but don't expect to be running around in high risk without being hunted by a team. I also don't really agree with your time line (2013 overheads), people were using overheads in tribrid as early as 2009. It wasn't as common, but in 2011-12 it got pretty big on mains for tribridding. Hybrids don't really exist in deep wilderness anymore. Turmoil was really strong so it made mage/melee really viable and soulsplit + yaks made hybrid fights without overheads more popular as well.
This version of the game has a LOT of dps, and it doesn't have things like soaking or BoBs to mitigate the damage you take so playing more defensively has become the meta. Games evolve and RS is no exception unfortunately for some people.
To answer your question though, if you're looking for an account to solo pk deep wilderness go 75 attack at a minimum. Claws are great for fall-in pking, but you lose all KO potential once you spec and 60 attack isn't that accurate.
