BOTH r good for pvp both r good tanks
btw for warrior warlock build only 1h skills r enough so its easier to switch weps wen needed
as for warrior cleric...probably the best tanks around and hve an obvious advantage over warr/locks
as for weps if you want to take 2h as ur main wep then cleric is probaby a better sub since 2h lacks defence
also 3 wep warriors cleric r good but 2 wep can also work so its upto you on how much u want to farm for em
