Honestly, i can agree to a large extent... u do sit there and think meh whats the point and there is a mass increase of nh in the pure world now which there never was before. In fact 80% of pures out there who pk everyday are nh and will pray first and tele when out. So i know exactly the problem but meh... i think your methods are a little ambitious or weak.
If you wanted to outright say look, in the modern day scape there is no point not allowing certain things in single solo pking where members go out and do w/e they want... So we are allowing them to teleport pray etc and so on, we do not approve of it and try to encourage not doing it unless fighting scumbags but essentially they are old and dead rules throughout most of the pure world. However, when fighting with clan mates and as a clan teleporting is simply not allowed because tbh clans fail when half their members are just tabbing out as soon as they are piled lol...
Tbh id of said meh, w/e do what u want etc you have justified it and if your members accept tht and enjoy tht and people looking to join cpr like tht fair enough.
But, the way you have done it by saying oh we can do this this and this under these circumstances just seems a little pointless and policing it will be next to impossible or a complete ball ache. Just go all or nothing tbh mate Nh solo and honour with clan not a wishy washy well kinda nh when solo but not nh etc if u get me.
Same with the 30 defence though, hypocritical to state that 30 defence isnt pure whilst allowing people to remain in ur "pure" clan with such a defence level and higher. Make them train up new pures and allow them to use these mains until they got new pures, if they cant do that for your clan then they are not good members and you should just get rid anyway.
My view on the matter.
P.s. i do heavily agree with your point about most clans not giving a **** about their own members but expecting you to punish your members, however its a vicious circle and il think tht bout ur clan so then u will think tht about my clan so no members get punished and every1 nhs and then sum1 else gets involved etc... just goes on and on. Sometimes u just have to think, am i running this clan for me and my members and for our enjoyment or are we running it for other people to judge, flame and for their enjoyment lol.
