Population started declining rapidly prior to HoT, long before Warclaw was introduced. Good thing Anet didn't listen to those that vocalized against Warclaw, because Warclaw in fact drastically helped roamers. What warclaw didn't help was gankers, 2 completely different identities. Warclaw easily helped to ninja towers and camps easier, but gankers.... lol.. good luck trying to linger around in the enemies 3rd when your dismounted trying to kill someone clearly not built to match you. On comes along a couple noobs and pounces on the mighty ganker and they die. Where this is all stemming from.. gankers absolutely positively hate the fact they get pounced on and instantly killed before rallying off a guard or some ambient deer or skale kicking around. The simple solution isn't to remove warclaw, but stop trying to gank and do something useful instead like actually roam. Roaming is not just about taking camps or objectives, it's about using those objectives to make good fights, and most of us are looking for outnumbered. Most of us will never attack someone alone who doesn't want to fight, because it's just not fair and not interesting for them and for us.In addition, you're talking about ganking like it was only the roamers who were making that, it's also the case in the zerg players, who could do anything for a loot bag. When you say that the warclaw helps roaming and makes ganking harder, it's totally the opposite, it helps zerg players to gank a little group until it dies, like it helps some roaming players to isolate someone in a zerg and ganking him just by pressing 4.Like Justine said, you cannot change the bad behavior of players, the ganking exists in roaming and also in the "zerg community", but you can change the game in order to reward skill : if a player in a zerg knows what he does, he'll be positioned in order to avoid any ganking, he should not be punished by someone unmounting him to isolate him ; if a roamer kites well and isolate someone, he should not be punished by a player who was too slow to follow, and OOC in order to catch him up.
