as we all know, when we kill a lot of players we take ban on the account, because of this there is the trap to make the person take ban, I believe that instead of a ban on the account should be ban on the character, or he get another type of skull, like the tibia black skull.

a pyromancer can't feel safe playing, because he can reach 9 invisible rogues from his side while he hunts, and when he uses the inferno spell, he will get ban, not on just the pyromancer, but in all other characters in his account

hope it can change

I would rather fix it so no one got banned, population can be a great thing.
3 second delay on players hit from invisibility will fix that while giving just enough time to think what to do next.
It is much better than just banned before using a spell and wondering what happened.

Also, put 3 second delay on players who freshly log in.
This will make it so you do not have ban traps.
3 second consistency will help solve a lot of problems.

If a player takes too many frags, instead of ban, make a different system.
Make it so they cannot participate by attacking in pvp, but they can be attacked.
What a great penalty, right?

This will make them pay off their second penalty, which is slightly more than black skull.
That is, if they wanna pvp or take so many unjusts past the limit.
