Tracking need the entire formula reworked. People complain about JoT tracking but in reality tracking is just broken. It serves no practical use for survival, combat, resource gathering, it's a low percentage at gm to find stealthers. There is a nice long timer on it, and you have 4 options to track for. A stealther hits hide and walks I know there is a timer on hiding but it's not such a big deal, also most stealthers are ninjas for smoke bombs, which helps them hide in rough situations.
Anyways we know all this, my thought is a passive tracking skill. If you walk by someone stealthing why not have an arrow pop up suddenly? You see his footprints in the dirt and suddenly you know there is someone there. Makes sense to me. A stealther can switch between animal form and human form constantly, much much faster then a tracker can hit track for player then track for animal, so this would be a cool adjustment. I'm not saying it should be every time but have it scaled vs the players tracking skill.
Another option I think would be cool is to give a tracker more ranger like skills. A ranger to me should be able to tame certain animals. If a tracker could control a nightmare for example think of the possibilities. I am just using that as an example, but they should have some sort of usefulness associated with the skill in terms of survival or damage. I know tracking increases deathstrike damage (or used to) but deathstrike already requires hiding/stealth/ninja to use. It just isn't a practical association. A minor taming chance would be awesome...think of bake kitsune from a necromancers wolf summon.
Tracking means finding people/animals/monsters. So trackers should gain some sort of a damage increase vs something tracked. If you find a person stealthing you should have a slight increase to damage done scaled on how much tracking the person has. Monsters and animal tracking would become a viable skill. But knowledge is power and if you know where something or someone is you should be able to have an advantage. This however could be an issue in pvp, but in terms of monster tracking it makes total sense, it makes tracking viable in pvm.
Have tracking make smokebombs fail. If you have 100 tracking skill then someone being tracked should have their success chance to smoke bomb scaled against the trackers tracking skill. A guy who is tracked by JoT can still smokebomb, but a guy who is tracked by a gm tracker fails 50% of the time using a smokebomb. (Just throwing numbers out here).
Thats all I can think of now, I will most likely get ripped apart by stealthers now,

but something really needs to be adjusted with tracking to make it viable. Tracking + Detect Hidden to find hidden players isn't worth it. There is no reason to track animals or monsters either. Hide and Stealth are awesome don't get me wrong, but the counters are weak in comparison, someone can hide and walk around hidden but to find them you must constantly spam an active skill, have a less then 50% chance to find them and in a lot of areas tracking targets just don't work. (despise champion spawn). Also tracking/detect helps in no way what so ever for survival or damage.
