You just proved a fact that has been floating around since WotLK; just because 95% of random battlegrounds are comprised of casters (mage, priest, lock, the list goes on) does not justify adding a 15 sec CD to one of a warriors only magic reducing/mitigation spells. You also seem to justify the, let's call it a re-nerf, based on multiple casters on a single warrior. This alone does not represent the majority of PvP encounters. As a WoW subscriber who has only played and leveled a warrior (until my recent Resto Druid) since WotLK (yes WotLK baby) I've only used spell reflect when i felt crafty enough to spam a macro that HAS to be mashed multiple times to even work, this doesn't even take into consideration the 50ms (on a good day) server lag that makes me reflect a pet bolt, or a 3k ice lance.Spell Reflect is one of those mechanics that always feels weak to the warrior and overpowered to everyone else. We ran a bunch of internal BGs and Arenas and it was pretty universal that the casters were constantly having everything reflected if there was a warrior in the area.
We're still tweaking the Mass Spell Reflect talent. We want it to feel awesome, and we think that is a good way for warriors who want to be great at reflection to be able to make that commitment. Our current thought is that Mass Spell Reflect is a new ability (meaning that you'd have both spell reflects) and doesn't require a shield. We like that seeing the warrior strap on a shield signals to the caster that reflection is a risk -- the alternative is that sometimes your spells just bounce back at you, seemingly at random. That logic works for the core Spell Reflect, but already doesn't work with Mass, because you don't see the shield for the warrior's allies. Decoupling the two spells also lets us individually tweak their durations and cooldowns.
That being said, I can see how a "Mass Spell Reflect" will entice warriors into putting aside the anger mustered by the 15sec nerf, but I feel this isn't something that should cast aside and masked by an ability that allows a second reflect.
While this seems like a flame it isn't, I'm simply concerned that this is being taken the wrong way, warriors have always had a lot of "bitchy" issues in the forums about nerfs>buffs>nerfs and yes, it is kind of annoying, but a class that is second to none in WoW as far as diversity deserves that "special feeling" of reflecting a [Polymorph], [Cyclone], [Hex], [Fear], [Lava Burst], .......yah, lots of casters. Sitting in a Frost Nova/Pet Nova/Gul'Dan/HoJ... and getting obliterated without wasting our only 4min CD is insane.
That's my two-cents on the matter.
P.S: this topic is void of anger towards mobility, specifically a 12 sec charge and heroic leap that only works on near-flat terrain, but this in itself is still a topic that needs attention.
