I want to start this post by saying I am NOT a career PVP player. My friends and I do PVP roulettes and CC together for fun after we all got our Garo mounts (I know we're sick people and probably in the minority, but it's fun to hang out with friends and blow some steam).
I'm sure I'm not the first to say that Naadam sucks royal ass. It was bad before, given that it all hinged on having a coordinated team that knew what they were doing (which is hard to come by when you just queue into PVP on any given night).
But now there are teams that are using tank invuls (ex: Pally's Hallowed ground) along with a tank cooldown (ex: Pally's cover) to put on a teammate (ex: DRG or SAM or any other job) that is getting the node. This literally makes it impossible for other teams to stop that node from being captured. It ruins that mode for anyone who isn't on the OP team (I just did a match with my friends and saw this being done by one team over a half dozen times at least.
Please, for the love of God dev team, address how these tank actions can be used in PVP. It's extremely frustrating and unfair to anyone who isn't on the team that is steamrolling everyone else.
