Summoning presents a challenge. It would be great to be able to drop anything at any time, exactly as in the rest of osrs gold buy. The restriction of pouches in this manner feels strange in pvp realms. I have no solution to this, maybe the best option is to simple keep the pouches in the form of "pouch in invent, combat increases"
The most important thing is that you cannot have pvp wilderness realms. Never. The thrill of the wilderness provided one thing that pvp/bh realms were lacking, and it was the best handling I have ever seen.
Pvp meeting pve players. It was possible to utilize the resources available, like treasure trails, runes and dragons to earn rewards. However, this was not a requirement. My above point for the quests is that every player should have access to that type of content, but making some worlds "safe" is a blunder entirely. It's the most crucial thing. If there's a secure place to stay away from attacks, that defeats all the purpose.
Since there's a safe one just one step away, no runecrafter will use the dangerous deep. The zombies who are armored are able to run on safe planets and then move to more dangerous ones once they are out of the wilderness. This is applicable to all worlds. This is an appeal, don't promote the idea "safe" realms.
Wilderness and Free Trade
Wilderness and free trade are currently being discussed. What happens to the things which were designed to replace it? A quick background... GE- was founded about a year prior to the infamous updates on free trade.
In the beginning, armor of rs3 gold ancient warriors was designed like statuettes. The pvp drop was so bad back then that they made them luck drops to ensure you could get these items.
