So awesome getting spammed by this game, just to login and have to fight people that are level 300. Been 3 years since I signed in, now I remember why I quit. Almost no one is on ever, why even bother trying to grow a community when there are so many issues that will prevent any new players from even bothering.
So you've played for 3 years and you haven't noticed that levels is irrelevant. All it means is that the opponent you're fighting has lvled and fought more. It's not like his folrart guardian is going to be stronger than your folrart guardian magically.
I agree that there's a problem, but not the one OP stated. It's simply hard to account for the player experience difference when the player base is so small. I for one would be happy accepting a handicap in my matches against low level players.
When the end comes, and enemies are rushing in from all sides, I will be at your right hand.
