Right teepees, any angled posts, carts, tree stumps & logs, rocks and probably other structures can be jumped/ sprint-jumped onto. That's why I said fixing one post will not solve this 'can of worms' problem that making changes to War server will/ has opened.
I assume Xsyon will just 'fix' each structure as someone decides to report each one which for years no one has had a problem or concern with until now. These nuances, in my opinion, make the game interesting, reward trial and error experimentation and exploration and invested time unlike the mindless grinding of skills.
But sure, lets just get rid of ALL of it, dumb it down and sterilize it. That's a great meme to propagate. What the heck, I'll give it my vote as well...if you can't beat 'em join 'em.
