NOTE:This is my opinion and mine alone based upon what I've seen and encountered whilst PVPing
Here's a scenario: You are a level 40 player lone wolfing Cyrodiil hunting stragglers when you come across a level 10 and level 30 player. Both are unaware of you as well as unaware of each other. Who do you attack?
Chances are, you're going to attack that poor level 10. And chances are, you'll win. But, have you ever considered how easily the tables could turn simply by using your own tactics against you? It is a known fact throughout every competitive PVP game that lower levels will always have a target on their back, they are weak and defenseless compared to others, and this could also become their greatest strength. Let's say that lower level is running with a group and they saw you before you saw them, now everyone in that group stealthed except for that level 10 who is baiting you in -- and you just walked into an ambush. Another scenario could be the level 10 is near some guards, not close enough to aggro them towards you, but close enough to maneuver behind you and use a knockback to throw you into the group. Now you have the more powerful guards, as well as that level 10 to worry about.
It always fascinates me the tactics other players adopt to out think and overpower their opponents. If there is any take away from this I hope it is this: Be aware of your surroundings and how other players perceive you, it might just become your advantage.
Now what are your favorite tricks and tactics to win the fight?
