All I do is play pub TO. And, I’m yet to see any intentional king griefing, that being said I am usually playing for the attacking team. And, as an avid attacker, I love charging at some random agathian guy on one of the flanks and striking him, then suddenly changing direction, jumping from the balcony at the last moment and making a beeline for the king through a couple more of clueless defenders. Once I’ve reached him I can use to my advantage that half of the defenders will doubt attacking me for the fear of hitting the king, the other half being lmb spammers that do most of my job for me. Putting reflective damage on him would make this strategy mostly useless.
If it was me, I would also enable damage on the peasants and barricades for the defending team, it’s just common sense and would make the game much more fun. For instance, countless times I would be breaking down the cave barricades to the queen’s family, when suddenly an agathian would pop out and start attacking me, I would continue attacking the barricades, while at the same time trying to dodge the agathians attacks and at least half of his strikes would hit the barricades. I do believe those kind of misses should be penalized by affecting the barricades to some degree. Obviously, griefing is a big concern here, I just wish it could be kept under control some other way.
