I personally loved Warhammer because of many great things. Like tanks that matter in pvp with the guard and taunt mechanic, shut down the enemy city and it's instances for a few days if the city raid was succesfull, Keep and fortress fights with backdooring, a pretty okish mechanic to favour players that face a zerg (against all odds buff which granted up to 400% more renown and xp), leveling was possible with PvP only if you wanted to. The detaunt mechanic was pretty dope too (-50% inc dmg from a target with high cd) Facing a pick up zerg with a proper 6man and snacking the sweet renown with the aao buff. Fun times i miss them
