2.) As everyone plays like a Sissie and camps rating the only way to get participation is to force it.
3.) Rating decay is a good choice, but WoW's concept always was to increase and not decrease. I think most of us, at least me, would prefer rating decay and fixed gear for everyone, like on the tournament realm. Combine that with short, region-wide seasons or in other words, make a permanent tournament realm with short seasons.
4.) Until that we have tournaments for competition and live server arena/rbg for the grind.
2. The people who camp are maybe 0.05% of the overall pvp population. How does forcing that 0.05% to play suddenly increase participation? _Forcing_ people to do stuff is not a solution to anything.
3. I'm quite sure most of us would not want a rating decay system. What do you base this on?
4. People don't play the game to grind afaik. Might be wrong tho. :PPP
