Since sneak skill was started to be used again, there is a problem involving "items from the ground disappearing", masses of sneak looters waiting on worldmap, so in case someone dies, he relogs to his sneaker to loot the shit out of the battlefield.
Sometimes you just see as stuff disappears from the ground, but you are unable to see or shoot the one who is picking it up. When they see you are closing by, they just run away. Even if you are able to see the guy for a moment, he can run past you and 3 hexes after that he's no longer visible. You try to catch him but it's too late.
So, sneak skill has become somehow stealing skill when it comes to take stuff away from the battlefield.
I suggest two possible solutions to this problem:
1. When you pick items from the ground or loot someone's corpse, your sneak is automatically deactivated. You can activate it again on normal conditions.
2. When you pick items from the ground or loot someone's corpse, there is made a check involving your Steal skill (for every item taken). If you succeed, your sneak is still on, but if you fail - your sneak is deactivated. There is no option for anyone to have super-high Sneak and super-high Steal skills at the same time, so if someone is planning to make 300 sneak 300 steal char, then.. well, yeah. Also, if someone wants to have sneaking thief, then he will be unable to make him a fighter (as a grenadier) too.
Before someone attacks me personally that I only use my dumb big gunner build, I would like to say that I have my sneak alt for at least 3 months and I was able to steal fuckloads of stuff on numerous occasions.
Also please don't post here about "BGs on sneak are unbalanced" or "sneak is overpowered" or some kind of such shit, this thread is only about looting and picking up items while sneaking. IMO sneak is balanced at the moment.
