This "cohesion" thing should be removed and a better way to deal with whatever problem this attempts to address should be developed. This current load of crap is so bad that it even looks like a temporary fix for something that never got finished. It's ******** to annoy players over and over again every day with this thing because a better fix hasn't been come up with after all this time.
It can be a serious pain in the ass and it has gotten chars killed before. I could take screenshots where "Cohesion" error messages are scrolling up the side of my screen. I can cast a gate and then never even make it through in some cases and it disappears, and I have to re-cast the thing.
Another one that was introduced wayyyyy back, say 1999 or so, was "You must wait to perform another action". I remember the UO client without it. It was good, quick, and crisp in terms of what you would be doing with items and tools and things back then. The trouble as I recall it was that occasionally things would get mixed up and the client would be confused, maybe even a freeze-up of some sort, I don't remember the exact details now. Instead of making a server-side action queue or something that didn't put the smack-down on the player, somebody picked THAT GARBAGE as a solution to players clicking things too fast. When I first saw the sick effects and the now-transformed client, I thought to myself, wow this has to be a temporary fix, this sucks! But then I saw the game in 2007 and I was like woah, they never cleaned that mess up. How ********.
