I'm all for the thrill of doing HC/Warmode, but there should be consequences if a max lvl wants to repeatedly delete numerous days of /played time
Also; if you dish it out, you better be able to take it.To avoid lvl 55/60 whatever camping flagging spots or ganking/hunting lvl 1-40 (for instance) on HC. Especially considering crossfaction.
EIther one or both of following features:
1) Only allow engaging in PvP when target is not grey level.
2) Enable Warmode and add debuff (that does not persist through death) to the player if they kill a HC player in PvP. The debuff prevents disabling of Warmode for 7 days /played time or 24 hours /played. Something like that.
