Give each player a skills like this
/skill PveOn : Pve is activated within specified "PVE" regions for X minutes. Failure to recast this skill could result in PVP damage.
This could also be increased by giving people using the pve skills some special physical characteristic so that players know when that player is pve activated.
( in cases of sneaking to jump players)
MY personal opinion is that pve truly does ruin pvp.. and im sorry if you disagree.. I have had this opinion since the first disappointing day of the pve release. the problem is that pve is the dominating portion of the server now. and quite honestly the server would be better without it.. If people want to pve then they should be able to but they should also have to defend themselves in some way.
Lets just revert back to the bastion/early haven.. I started playing in the end of bastion and had no option but to hide, dodge, sneak, evade, fight (or try to fight) to stay alive. I miss that. I really really miss that..
So.. you remove pve.. what happens then? Im sure some players will leave.. but most will stay and learn to pvp and adapt. and old players will come back
NEXT. You should consider the fact that PVP makes the server $$$$$.. people in pve dont have to level as many things (or worry about leveling quicker) so they obviously do not tend to buy boosts. now.. pve creates less pvp.. therefore pve makes the server less $$$$
pve is to pvp
as Broke is to not broke.
Take it from a business student- Create a demand for your shit and you will make money. pve is not demand.. it is just.. pve..
Last but not least.. If you build it, they will come.. assuming shit gets fixed
Thank you ,
have a nice day!
