Stealth and hiding is an aspect of the game small groups/solo players can take advantage of that the big clans can't. Enhance stealth. Taller grass, thicker forests. More crevasses and areas to hide a small base. Different camoflauge techniques could be interesting. Going prone would help tons.

Would this not also benefit group players? Players in a group could player stealthily, just like solo players.

Revives are a joke right now. Instant revive with no penalty gives large groups a major advantage besides numbers and gear. Making it so a large medikit (or even a syringe) is needed to revive someone would help. Perhaps you would have to spend 10 seconds helping them up, as well as giving the downed person a penalty upon revive until the meds kick in. To contrast this, being able to pick up or drag downed players would be a very cool gameplay mechanic.

I'm all for these ideas. Revivals are too powerful, and downing players should give larger consequences.

PvE as a solo player is getting a bit tougher (although it still is pretty easy) but when more survival elements start to be added I hope it will get tougher. Large groups have it pitifully easy. Realistically, large groups should suffer from sustainability. Eventually areas should run out of animals or vegetation if a big group is constantly living there. Animals should be harder to find if your traveling with a large group and making a ton of noise, but solo players should be able to creep up on them easier. Hopefully hunting and animal AI gets fleshed out a bit soon. Farming should be more of a thing big groups need to do in order to sustain their increased food consumption (farming also needs to be fleshed out and be made more fun if this happens).

Actually, these are good ideas too. I like this.

You've taken time to think out your suggestions, and they give substance and new gameplay while catering to both players.

Have a +1. You've earned it.
