id do it more like 8x 97 8x stat and 99 hp based for better odds its not like that many maxed pure stakers nowdays like it used to be 10 years ago youll hardly find fair stakes and ppl with 80 99 60 would have better odds on you tbh
Overpowered accounts like that only get stakes against similar stat accounts. Most people aren't stupid enough at flat 80s stats to stake a build like that. The only other people that might stake you are zerker accounts which don't make up a big majority of the arena.
The best scenario is just to get maxed combat at this point as that's not even a good account for x'ing as it is. It's already 99 attack / strength, so that's probably the best solution at this point. If you're again 50 / 50 staking, then I wouldn't recommend training that account up unless you're going to end up selling it / using it as a main for personal use.
