more skills and roll dodging no longer reveals you from stealth. so as a necromancer i can stay in the shadows and cast blastbones or ressurection ult from a distance...
make the legerdemain into the official sneak tree where if you are master thief you can effectively reduce your detect radius to zero(standing on the edge of a detection skills aoe but not inside wont reveal you) and nerf npc ability to detect those with high sneak skill.. to offset these changes you could make it so wearing medium or heavy armor would make noise effectively increasing you to be detected easier....
want sneaking to be better and more worth it for more classes other than nightblade.... closing the gap between gankblades and gankers from other classes is important imo more freedom in stealth can remain nightblade specialty but ill be damned if i cant sneak around a keep or resource without being targeted by the npcs as a master thief from a different class....
just opinion
