Best idea for making this game worth playing! I love seeing people who want more out of dragonball mmorpg than grind torment with some arenas for pvp.
Your idea makes sense. It would make DBO feel more DBO. People would need to cooperate. Imagine teaming up with your friends to defeat some higher lvl dude who PK'ed or stole your farm. (Goku and Picccolo vs Raditz).
Open Pvp Benefits:
-Action between boring grinding and quests
-Reason to play and acctually get proper gear
-Reason for staying in guild
-Cooperation and rivalries
-More in line with Dbz theme. Yeah we all know Goku is a radish farmer, but which one he would prefer :
a) growing radishes (PVE)
or
b) fighting bad guys (Open PvP)
Open PvP minuses:
-Some p#ssy kids crying and yet still going in for some PvP action themselves (just look at all the moba games "I was farming in my lane and you killed me bhah bhah bhah).
What I would add to your suggestion would be 2 different modes for open PvP.
Looking for a challenge: after you enter this mode you can fight other people who also entered this mode with no penalties. Just random fights in open world. Good sport.
You want some challenge - you get some challenge.
Looking for a trouble - mode you mentioned where you can fight anyone but anyone can fight you toowith penalties.
Edited: Some restrictions to consider.
1. Safe zones - the 3 starting areas, Major NPC areas should not be available for PVP.
2. Players with lvl gap by 20 lvls should not be able to attack each other unless they are both in mode "Looking for a challenge" to prevent low lvl PK spam and yet still give teaming up oportunity for low lvls.
Comon! Make this dead broing game more thrilling and worth playing!
