here's how it works:
1. there will be a NPC that teleports you to a specific place or area with giants, including super bosses like CW, LCA, red meteo, razgul, kheldor and others. also including special monsters that only be seen when doing quests. (like ivilness quest)
2. the player(s) will select which area he likes:
Area 1: all giants in Flaris, and in Mars Dungeon
Area 2: all giants in SM, Rhisis Garden and in Ivilness Dungeon
Area 3: all giants in Darkon 1 and 2
Area 4: all giants in Darkon 3
Area 5: special giants in The Wilds, The Savage Wilds, Animus and Cursed Animus Dungeon
Area 6: super bosses
3. inside in each area will have pang buffs.
4. if a player dies, he/she will be respawned beside the pang buff of the corresponding area. of course he/she will loose XP if he/she doesn't use a SOB
5. all monsters are aggressive and have rage mode (x2 damage if HP drops to 25%)
6. all monsters will not heal its HP
*IMO. this suggestion, when implemented, will kill the boredon of some players that are tired in pvp and pwning other players inside the arena. lol
