Okay, here is an idea in lieu of what Johnathant said. How about I add an 'ironmode' which you can toggle on which makes your attacks half as effective, but raises your point cap per round to 3000. So it makes it a lot harder to do damage, but you can potentially gain 3x more points per round than normal.
Neat idea but doesn't sound right. So it makes it harder for a said player to do damage, raising the point cap for them which they don't need since they've already earned all the points they want. Probably all the titles they have as well. In addition, it means using a miniboss is less effective and I know there are some who'll abuse it to troll others. Literally the only thing that anyone could get is a pet, and for instance if you have a really good player, able to get 3k points per round(or 3.5k, since there's a 500 bonus if you get the killing blow), you can get a boss coin every 5 rounds. On a decent playercount I manage to get around 6-8k points worth of damage as overweight. It wouldn't take very long for anyone to get a pet at that rate, then they'll come right back to here after they achieve it.
Edit: Without further work, this would actually allow people to point farm via any means, probably by backstabbing with a 2k point profit per round. I've seen people attempt it all the time which is why I raised the point loss to 1.5k when a boss dies. Raising this to 3k doesn't seem reasonable. Instead of the normals having the "ironmode", the boss could have it instead. Rather than getting 500 per kill, it'd be 1000. Half damage would apply and damage would make a player lose probably 3k-5k. Unfortunately even if you cut most bosses' attacks in half, Badspot can still wand for 500 and push people to walls easily, same can be said for Ephi, Rotondo is suddenly more useless than before, Medusa doesn't stand a chance(with 40 melee and 60 ranged damage). Other bosses would end up ruined or get by alright, some completely avoided like Sky Captain for instance. 65 damage per bullet, cut in half? A rocket that can't oneshot an overweight normally, also cut in half? Basically if ironmode was a thing for the boss, it would be a non-stop stream of people playing as Badspot or Ephi. I don't view it as a good idea for either team now that I went through it.
