This definitely is a touchy subject for some.
We have the PKer's who are doing their thing, which is of-course, heading to the wilderness and engaging in Player vs Player combat, and if successful, they walk away with the opponents agility tickets, resulting in them making some sort of profit, depending on how many tickets the other person was carrying at the time.
Then we have the Skiller's, who, once again are at the Wilderness Course for the sole purpose of gathering exp as fast as they can to move onto the next best option, which for agility would be the advanced courses.
With being a skiller myself, I personally feel the frustration that other skiller's feel, when they are minding their own business trying to get some fast exp so they can level up then get the hell out of the wilderness, come across someone who is solely there to interrupt your training method and instantly kill you, (because half the time you enter with nothing other than the Agile Set if you have it). But with this comes the RISK. We are ALL prompted with a message when we click on the agility wilderness cause which states "If you proceed further, other players can attack you". We then all click proceed / enter wilderness knowing that, if we do come across said pk'er we are likely to lose our tickets that we have gathered.
I definitely support the fact that some form of time period or other means necessary should be added (so players can't use the tickets before they are killed) as we accepted the fact that we have entered the wilderness. It's fair game, and if we have the chance to use the tickets before the pk'er has killed us, this just feels like an unfair advantage.
Because also, we wouldn't be able to run from level 50 to level 20 wilderness to teleport out of there fast enough either, so we should either face the fact that the pk'er won that fight or take the loss and lose our tickets at the same time.
Support +1 for some sort of timer to be added once combat has started.
