I think Ryme (may I call you Ross, dear sir?

The minis should be VERY chaotic. Meaning that any new player could dominate well, given, say, a month, and an understanding of the PvP system.
However, a current player should not be subject to loss if the player is devoted. Hence the many "within the last month" suggestions I'm making.
Taken from KoL (real AND suggestions)
1) Fashion. Clearly does not require unreachable dedication to win. Attacker should win if a tie happens. Why? "You and your opponent both match in your fashionable suits, but the judges are impressed by your attacking stance."
2) Trophy. In this case, a merit badge mini. Not sure what happens in case of a tie.
3) Stats. Self explanatory. Just put a variance on the compared stats and bam.
4) Purity. Gotta balance those stat minis. This mini is questionable though.
5) A suggested mini. Elemental comparisons. Compares elemental resistance of course.

6) Consumption mini. Compares the number of foods AND drinks (I don't think it's a good idea to separate the two like in KoL) consumed in the last month.
A month would probably be 30 days.
ME! ALL ME! + DGW! For the most part.
1) Player Slayer. Compares the number of unique victories in the past month or so. Ties goto the attacker...maybe.
2) Perhaps add in just a randomly generated mini? Coin flip, possibly?
3) Just...possibly a comparison of the number of quests completed. This is very subject...having more quests that can relatively fit under two weeks seems too much.
4) This is mainly inspired by dead_guys_watch, but it's awesome. Exploration mini. Compares the number of unique visits to ingame locations (that require a turn, minus resting).
5) STOLEN FROM DGW AGAIN. Risk taking. This factors in your opponents level and stuff and compares difficulty scalings. As in, it compares whether you're choosing harder opponents to attack and such.
Now, outside of the battle is the war...
1) Calvinball. This is originally Hogulus' idea, but it ROCKS. There is a special item that can ONLY be transferred by winning in PvP. It can confer some sort of bonus, I suppose. Your "hippy stone" cannot be repaired while in your possession too.
2) Limited number of attacks per day of course. Increasable or not, possibly.
3) Penalties for losing on attack. Maybe defense. If you get KO'd you should receive some kind of beaten up penalty.
4) A hippy stone-like mechanic! Of some sort.
TBC...in later posts.
Suggestions? Thoughts?
