This whole Meta Party thing is hurting me. x_x

[NoctusT]

So there are 2 types of meta really. Progression meta and speedkill meta. RDM will always be a part of progression meta due to the amt of raises you have. So I wouldn't worry about people saying "rdm is terrible".

The speedkill meta is all about ranged dps and melee. Casters don't really have a spot there and that's the devs' problem. Just FYI the speedkill meta only directly affects people who speedkill who are a subset of raiders who are, in turn, a subset of the entire playerbase. So MCH will currently have a spot in the speedkill meta unless the party is running triple melee which brings problems of its own. So it goes something like:
(Player base (Raiders (Speedkillers)))

So the people who think the "speedkill meta" which is what they normally refer to as "the meta" is the be all end all of raiding are actual morons as most of the player base dont play at a high enough level for the meta to be actually relevant for them. Stick to what you like and get good at that job. If people are rejecting you for playing RDM (which is, as I said above, a really good job for progression) you don't want to be raiding with them anyways.

It helps if you remember that most of the people talking in the official forums and reddit are idiots. That said being able to flex more than one job in a raid environment is not a bad thing TBH. Being able to play RDM and MCH at a high level is quite valuable as many players (including me) are one trick ponies. But as you pointed out yourself, learning to play RDM well will benefit you more as I'm guessing that you're new to raiding. You can, of course, learn MCH once you get used to playing RDM.

So TL;DR - remember that most of the people on forums have lower IQ's than baboons. RDM is really good for prog and comes with its own physical DPS raid buff. If you love RDM the most learn to play it well and don't worry about what people say. You don't want to raid with the people who only focus on the meta anyways since they don't understand why those jobs work so well. Being able to play MCH as well is not a bad idea though. But take it slow and get used to RDM first.

I hope this helped. GL for this coming tier and remember to have fun!
