In Battleground disable Cards, etc would be good, but in open world they should stay. It was fun and good to have them. Only idiots would disable them in open world PVP because one-three players want it on forum, and others dont care.
Anyway PVP glory in MMO ale long dead, its not fault of tera, in mostly mmos PVP died, because players dont like play it anymore like in 2012 or so. Their places was take over by MOBA. Veterans can cry and complain about it, but they will not change the time flow and changes. As it is now i see here only several players again and again andothers just dont care, so... changes for severalplayers are not good changes.
Also Buschfunker as i see his posts is acting just like angry kid who insult wrong peoples because he dont like changes. You know what? Game is for everyone not only for several complainers here. You dont like changes? You are free to create your own game and put in it things thats you like. Also Devas can changes their games as they like, its their games after all, not yours. And if you dont like the changes they puts in u can find other game.
I know people here will not understand this and will always complain, but it not matter as only 0,1% total player base from tera (or even less) looks here and complain (PVP even less as PVP is dead in MMO and its iconic now), others who still plays tera just play it.
