My Dedication-Giving A Bit To Get Alot
This article does involve the Paladin/Druid community more but its easily applied to Warriors in certain places!
When you rolled a hybrid class you knowingly started something that could fulfill multiple roles. Having said that you should always bone up on the different roles you can fill and be current on them in tactics and gear.
An example of this I can share is with my own guild. Our healers had been away from the game for a while and we were short on healers.
My raid team had always passed me healing loot that our other healers didn't need. It was a "rainy day" mentality to it all. Which of course ended up panning out. Because I had picked up this gear I respecced holy and for that week I healed our Kara runs. Were we gimped? Meh, we were for the most part completely fine. We even made our first complete clear of the instance with me healing.
To be quite honest when I was first asked to respec to holy to heal for raids I was angry. I had felt that I had worked very very hard to amass a respectable set of tanking gear. I thought that I had gone above and beyond my expectations as a tank, and maybe some of my appeal coming from me being a Paladin. I felt that I was being pidgeon holed into a role I did not like.
But it was this very night that I had actually sat and thought about it. The thing I just mentioned above, I rolled a hybrid and should of expected times in which I would have to respec in order to help the raid as a whole. I've written about it and how one should spec out to help in the best they can.
The truth of it is that you can and should fulfill the spots that you are able to. This is of course to be taken in a manner that its within reason to do so. To rephrase that, it merely means if your raid team has a genuine need for a healer you should be willing to fill that spot if your able to do so competently.
I found because of my willingness to help the guild progress I was later rewarded. Our Gm at one point during the day said that he wanted the dedicated healers to get off their butts and raid, and that me and a shaman in our guild shouldn't be stuck healing when we can clearly provide better in our main roles. He gave me the nod telling me that I had been willing to help everyone out and that I was going prot for the raid.
This helps not only the raid out so much but you as well. Your willingness and desire to help the raid progress shines and your raid leaders and gm's see that. Just like any job you have in real life, you put in work and fill in for spots. The end result is that you get paid back for it. Your guild sees your a team oriented person, and because of that you raise guild morale. Having people that fill niches instills a feeling of family and makes for a tighter knit group for raids that is quite integral to success.
If your GM or raid leaders asks you to respec for a run, its normal to want to stay with something your passionate about of course, but don't shun it, its an chance to make your guild shine.
The most stressful, yet provides the most gratification..
