I'm not on Morrigan but I think it's all about respect.
Even though EternalSin may (or may not) be the best clan on Rhiannon, I will still not tolerate ksing. I have respect for others that play this game.. Enough respect to not rob them out of their hard work.
Anyways, IMO, ksing is turning up at a fight that another clan has already started and calling for your clans dps. 'Stealing' the kill from your opposition. I think the clan that tanks/heals on a boss deserves the kill, so whenever EternalSin find themselves in an 'FFA' with another clan, we almost always find ourself tanking and healing whilst our DPS are hitting away. Other clans don't seem to do this and just bring straight DPS to credit from another clans hard work, but I guess that is through lack of respect. Ksing to me is a type of bullying and I do not stand for bullying.
Also, everyone has my respect...... Until they lose it.
I'm not sure at all why you are posting on this thread but meh. Each clan has it's own rules for pretty much everything , and if those of you n morrigan do not understand Ava's ks rules yet , you have not been paying attention.
I will say this though, do unto others as they have done to you.
Often times I have the ability to ks mareth on bosses even solo and I don't out of respect, you earned it in my eyes , some other clans not so much
