You can't put the duels in pvp cave as a means of ranking, since amp plays a part.
Only the best know how to avoid multiple enemies and pick them off one by one. Try solo ganking on enemy land as a real means of skill.
A shaman can beat two lvl 20 rangers with amped bow and 5 in blessing easily, if you use skill.
Screen switching at the right time plays a part of skill. you are a moron and lack skill if you don't screen switch and just stand there while two rangers wail on you.
