This suggestion is two fold, so the post might be long, but bear with me.
1.) Currently NPCs are split into two main groups: 1 CH and 3 CH NPCs. This schism promotes people with 1 CH builds to create alts to fully take advantage of the system, and this is clearly something that the developers want to eradicate. Instead I propose a system that is already being used in TC, that is the "gear check", where an NPC would barter/talk with you if you have decent gear (such as leather jacket or desert robe). The logic of this is trivial, who would someone trade/ask for help from
A or
B? Not only does this encourage people to wear armor, but it also lessens the need for an alt.
2.) In complement with the first suggestion, it is also important to make low tier gear easier to acquire. Take for example the leather jacket, to make it you need to kill geckos and brahmins, which come in groups and killing even two is a daunting task for a newbie. Instead, with the addition of desert robes FRMs, I think that a desert robes should be a craftable starter armor that doesn't require you to kill anything, other than gathering fiber. Just think of a desert robe as analogous to a primitive tool, which is needed to begin hunting. In addition, I also propose that armors such as leather jackets/armors are dropped from NPCs similar to weapons (deteriorated of course). I don't see a good reason why this is not implemented, as it will not ruin TC PvP, but will help the starting player, and also encourage people with limited resources to still wear something other than their pajamas.
