But staking is already about skill..... People make staking specific accounts, which turns out those accounts are the exact same combat level as other accounts. So instead of being pure luck, staking is all skill. There will always be one person with higher defence, higher strength, higher attack, and always someone who either has staked longer an knows more or someone that cheats with the weapons.
I have a maxed mage boxer. It is level 98 with 99 def, hp, and mage. I make every 110+ x2 my stake because they believe I am lower and they can win. Now granted they are mostly mains so they aren't maxed, I naturally win because I have the higher skill and know more about mbing...
So I think the combat change will take away the skill (as in take away the maxed low level specific accounts ability to always win) and completely remove the sense of luck. It is all just a matter of who knows how to use the abilities of new combat better than the other person.
Just my take on it.
