This has been a huge subject around the interwebs since the announcement of them being in the 3.1 patch. I am biased in that I can't wait for this function to come in to effect. Our guild has 15-20 people with over a hundred characters, we are a super casual guild with a couple of more hardcore members but they really like our guild because everyone is RL friends. We only have 12 80's (10 people) in our guild, that's just enough to do a 10man if everyone is on, which is very rare. This leaves us very stuck in roles if we want to run stuff, with only 2 tanks and 2 healers at 80, it leaves those of us with those toons tied into those roles. I am really close to have 3 toons at 80; one healer(76) one tank(80), and one dps(79). So very soon I will be able to fill any of the roles necessary with very little trouble. But I am one of very few. This alone leaves me little time to experiment with different specs or to try different things with these toons because I really want everyone in the guild to be able to experience as much content as possible. With duel specs it will really help our small guild be able to cover more areas and fill in if we happen to be missing something at that time. I am not complaining about the situation we are in now. I love my guild and guildmates, We are always able to have fun with things even if we are wiping on the most stupid things. I am just happy that with this feature I will be able to have much more flexibility with my toons and will hopefully be able to move our guild further along into some raiding that I know most of them enjoy doing. So I thought I would post what my dual spec plans are for my toons(1000 bucks a pop, no problem, /end sarcasm).
mistrk; current spec: prot pally, dual specs: undecided
I just don't know yet. I have been sort of working on both a ret and healing set, I am not sure yet what I want to do, to many options(arena, pve heals, ret!!). This will be the hardest toon to decide and will probably be switched a few times just because thats how I roll.
chowyunfat; current spec: Boomkin, dual specs: Resto/Boomkin
This is the easiest choice. I hated feral, wasn't any good at it and have always wanted to try resto so BAM, here I am best of both worlds HAHAHAHA!!
Newguy; current spec: disc heals, dual specs: disc/holy
I love options, and this gives me the best of both worlds, I was one of the first to switch to discipline healing(yes before all the bloggers had jumped on the bandwagon, I specced it right after 3.02 talents came out) I love it because I was holy for along time and sometimes I miss circle of healing. Never liked shadow, and we have 2 shadow priests in our guild already.
Warriorbarbi; current spec: prot warrior(duh), dual specs: prot/arms
I don't know when she will get to that point but when I do plunk down the cash it will be so she can go back arms to pvp, I leveled arms to 60 until I could get shockwave and now kind of have her as my low level tank to help guildies leveling up in dungeon runs.
Iamthetick; current spec: beastmaster hunter, dual specs: BM/Survival
exotic pets/mad dps simple yet effective
Psychostick; current spec: demonology warlock, dual specs: demon/some pvp spec
He's only 56 I don't know enough about warlock specs to make any decisions yet, more BG then arena though.
Septictank; current spec: unholy DK, dual specs: unholy dps/ some tank spec
not sure, he has sat at 65 for a long time. I like the playstyle just not a priority right now. If I really want to get into arena I might level him up though
Happymadison; current spec: Frost mage, dual specs: frost/frostfire
I love frost, the aoe farming capabilities are amazing, and I have seen frostfire in action, that build brings the pain
I don't know when I'll ever level my rogue or shaman so no plans for them, or for my horde toons for that matter, I think that's about a big enough wall of text for today anyway, well that's just my 2 cents
