well, now that i've taken a breather, the encumbrance system is a good idea I admit. But, practicality and sensibility are not in favor with game mechanics.
If I can carry a max of 200 lbs with an 18 str, i have 6 or so bags at 60%, and I still can't carry 2 corpses at 130 lbs or such because they put me 30lbs over the 200lb max then it seems kind of silly to me.
Monsters wont wait for the whole 3-5 seconds it takes to drop added weight so you can carry your companions to safety, where in reality you could instantly drop a large bag of junk if you needed to to move faster.
I spent a year and a half in iraq, and trust me, if you need to pick up your companion and run to move out of harm while you are already carrying 130 lbs of weapons and lead vest along with radio you move. It has very little to do with strength and more to do with the urgency of the situation. One can take care of their companions in situations when needed.
Shouldn't have to be sending tells to clerics around the server to help a party because everyone died due to encumbrance , nor have to try and find another group to come rescue the first, mainly because either way it leads to meta gaming.
Maybe if there was a "body bag" or something which could be used as a dragging cart for bodies, though I am not sure that that wouldn't be exploited for other uses as well. So, it brings into the picture, why not have horses and such available to carry things in situations like this? Cep 2 is in, so we have the capability, and it would make a practical sense now to have a pack horse or mule for such situations as death or mining, and would still keep it all ic.
