Yeah reading the post I don't know what you expect OP, gear treadmill is a standard thing in the genre save for a few examples like Guild Wars 2, which also doesn't do level cap increases, save for those few, anything else will have this issue, it's just the nature of the beast, your gear is always going to become outdated and you will always need to grind for new stuff, the only difference is how difficult it is to grind for those new things.
