For the people who wants tips I hope i am not too late. Lately I been using two skills alot for WANTED and Alliances. That will be Disguise and Poison. For two reason why it give me the more points when i do both together.
when you in disguise you always get hidden bounes when you but you need wait while before you get the hidden bouns before you get the kill. 2-3 sec you gotta wait for in till you get hidden status. Also it's best way to get variety because you use stuff like this. Disguise is best way to get around the map with out getting noticed by your assassin as while it work both ways.
To use poison well it to let flow don't force it. I use poison in the Pre-Beta days and it won't work is you just force and get in there for it. Don't think about if it happen it happens poison give you alot points. If you don't use right or sometime lag don't let you use the poison use your trusty weapon to kill them.
If you don't wanna get noticed quickly by the your assassin. Walk take your time try find area where there a lot NPC looks at like you only run if you think your safe. Watch out for the whispers because sometimes they don't work so watch every NPC that you see the your screen. Sometime there NPC who are not there but yet you can run into them. FREAKY!!!!!!
I know my grammar sucks but hey I wanna help. I called this skills the Jackal mode
