Atm im Ilvl 492 with 2 blue weapon's
i know Fury is better then arms, but i have the oppertunity to get the 502 2h sword for cheap
do you guys think i shall do that and how long does it take before arms gets overrun by fury TG or fury 1h?
Basically, fury 2h and fury 1h are equal, even at a very high lvl of equipment, the difference isn't tangible. Also currently arms is much better than during 5.1, and really correct with a good weapon, just a little under fury on many fights. Then you could go for arms with this weapon until you get a second 2h and switch back to a 2H fury spec for example. However be sure to use correct gems and reforging as the stats priorities is not the same for fury and arms specs.
Whatever you chose, your spec must be chosen following you weapon at this level, as it is the major component of your dps
