It gives an incentive to level. The problem isn't how WoE mechanics work based on level. The problem is the current leveling / party system. If people enjoy leveling then it's no longer a problem if you're lower level in WoE and get destroyed, because it'll just make you want to get to 150 and it'll be fun to do so.
The GMs should work on the source of the problem which is leveling.
I'm just going to reply to this and then skip the rest of the next 6 pages...
Look, I would not call this an "incentive" at all. I would actually call it an ultimatum. Get to 150 or you will suck. Get to 150, or be destroyed. Get to 150, or you will never have fun in PvP. And then when you are faced with the -_-tastic grind from 90-150... people just lose interest in the game altogether rather than falling in the category of "being sucky" or "being 150". So that said, you are still right that the big problem is people not enjoying leveling.
If you have made it to 150, congrats at wasting countless hours of your life over a broken game.
