MabiPro: The Authentic Old-School Mabinogi Experience

You're supposed to NOT rely on the tendering pot as a source for -CP.

There are -CP gears and it's rare, there's other training site that does the same job; albeit slower, etc.
If you're struggling to stay below the threshold, you should've played better or simply give it up and go elsewhere.
I didn't complain when I can't train at zombie, I still made it to r1 WM (though having to kill lions for BOSS isn't optimal). Do shadow missions, run other things, whatever you see fit.

No comments on the pricing, I don't agree or disagree with it, that's for other people to judge

For me and proffing, it's fine as is, and ego repair isn't that bad unless you excessively use it heavily in combat and don't bother to prof. an extra spare alongside with it.
Plus, it goes back to depending on -CP just for your activity. You can always do something else to prof., and 5 minutes for 25 is pretty darn fast. Though that is a pretty easy way to go about proffing it.

We have voice-chat in the Discord server, and not many use it on a regular basis.

Sure, go ahead and edit if you need to.
