U can also use a prot warr but I guess prot pala is easier to handle.
When u use SoR judgement hits harder.
With 1dk 4rets however u want to use SoC because it makes u able to global multiple opponents when wings are up.
With the divine storm+SoC cleaving bug the setup was utterly overpowered.
Nowadays its still the best 5 man setup as a multiboxer but its not as OP as during the buggy molten times.
Thats why pvp on the open field is never balanced but always in favor for the ranged classes.
Spamming LB on a 41 yard range and hiding in the crowd works not only against multiboxer but against all kind of opponents. Same goes to MM hunter that shoots on max distance.
