I'm not seeing why it should only be Spider Web that you can't snap out of. Since there is no pushback in woe and no backsliding Champions are the only ones who can easily bypass them. They should be just as screwed over as the rest of us. Yes you can break traps but once you are in one you're basically stuck. So yeah in my opnion if Spider Web, why not all of them?
And nines for your information. I didn't make this suggestion because my guild wanted it. I made it because if you think about it (tough task, I know) it makes no sense why Champions and Assassin Crosses can easily just slide/snap out of these and go on their merry way. And also it would hurt Stalkers a bit too because if you didn't notice they can backslide out of things too. Basically it comes down to this (not counting pushback skills) 3 classes can just slide/snap out of these skills and 2 of them are the most OP classes on the server. I hope you get it now.
