Well its common sense to avoid stronger opponent
Besides server kinda low populated and its hard to capture good party vs party or mass pvp.Only exception is siege
If people see you coming with full pt they instant party recall and then starts chat : We got only 4 people active etc.
Then you go alone ,your opponet sees advantage in numbers and feels more confident to strike back
There is no such a thing as "skill" in l2
Better equiped,geared person wins
If talk about imbalanced class,then yes nekro are OP.but in that videos i saw from enemies as well nekros and tanks with 3rd prof
Sadly l2 is all about buffs
