Fury in ArenaFollow

Generally the lack of burst damage and Mortal Strike Debuff makes Fury warriors less effective than Arms warriors in Arena.

Arms warriors have more burst damage and MS debuff.

In my opinion, Fury warriors are better at 5v5 than 3v3 or 2v2.

I totally agree. I think overall damage over a long time(if you don't get cc'd) fury will do more damage, but they will heal through all of it with short heals. If you land big hits, the opponent will be forced to use long heals and their mana will be drained quickly.

Burst damage has also psychological aspect - when someone suddenly looses 70 % of HP in 3 seconds healer can panic or he can simply not be able to heal due to CC, interupts or simply not paying attention.
To add to that any heals he lands will be cut in half so he must use big, mana draining heals to compensate for it.

As for MS warrior in raids - MS warrior in raids uses either 31/30 or 33/28 biulds which lack Second Wind, TM and either PH or Sweeping Strikes.
You can still PvP with such build but it is not the PvP build - especially for 2v2 and 3v3. Still fury has a potential to do more DPS than arms and is not that dependant on situation. Arms looses a lot without WF totem or when fight is dynamic as Arms DPS is harder to maintain during movement or even imposible to maintain in such situation (slam has cast time and should be used exactly after white hit or it may even decrease DPS).

if you're fighting non-healer teams, fury is better if you have good gear. GOD FORBID though, if you play anyone that has a healer, or means to heal with and not have MS. Unless the gear / skill difference is PHENOMENAL you will have 0 chance.

I definitely would not go so far as to say that. I raided as an arms warrior for quite a while and I was doing a good amount of damage. (And no, my raiding parties were not incompetent or bad) I would usually be up in the top 6-8 in DPS, which is not amazing, but is also not bad. And I would definitely not go so far as to say and Arms warrior does comparable damage to a ret pally. All the ret pallies that raided with with my arms warrior did far less damage than me.

The main problem I experienced with raiding as an arms warrior were issues with raid utility (other than BF and MS, what do you have?). Ialaman, you probably have just not raided with a very good (not saying incompetent) arms warrior.

As someone else said, you may just have to get used to the respec costs. While they are quite a bit, you would probably only be respecing once every three or four days.

I DPS as Arms specc. I was top DPS yesterday (TK) and second two days ago (Gruul)...
Yes I care for my gear much more than others and work harder to have best I can get.
Yes I had WF totem up all the time.
Yes I buffed myself fully on every boss fight.
Yes it happens I am below top 5 but unless I OT or die early I am never below top 7 in 25 men raids.
Yes I was beaten by fury warrior with comparable gear a few times.

Still noone would ever say my DPS suks....

Get better ret pallies.

Yeah, like the others have said, neither is horrible at both PvE and PvP. One is just better than the other. But being Fury instead of Arms is a big handicap in Arenas.

If you're saying a great player will top out, at best, at #4-5 on the damage meter, then I would certainly say that class/spec combo is marginal raid DPS. Arms spec in raids just hasn't recovered since they removed the ability for Windfury to proc off any yellow attacks.

Remember, Marginal dps is still better than Crappy dps. The thing that makes it more worthwhile than a ret pally is that a ret pally's 3% crit for the raid doesn't scale nearly as well as Blood Frenzy's +damage for physical.

Eh, I didn't say at best. On melee focused fights (Kaz'rogal and even Anetheron come to mind) he usually runs #3, which is to say a bit behind me and our top Rogue. In terms of overall raid damage he's probably beating me once you factor in the 4% physical damage debuff. Either way the damage output is quite solid.
