Where is the evidence for a third subclass? Cause i really hope there is one.

Why do people think there's a separation between classes there isn't the only thing that's really different is the skill trees. The characters are what you prefer but the hunter is not a Dps class the titan is not a tank and the warlock is not the paladin/healer/mage whichever you prefer to call it. They are all awesome just some may be suited to your play style better than others that's it. But that's just my opinion there's no need to go spreading it around.

Everyone is dps and equally so, we can all use the same weapons. There is no tank, even a fully defensive titan would only be able to stand in front of something like a devil walker until it point blank hits you the first time. There is no healer, every class can self heal and everyone can resurrect everyone. Also, the traditional concept of aggro isn't present. There you have it, every build, regardless of class, is viable for raiding. Success depends on your actual skill in aiming and firing and team skills. Sure some groups might synergize builds, but it is not a necessity. If you are excluded based on your class you have encountered one or more ignorant fools. They will learn.

Bring the player not the class.. After many years of raiding you should know this and so should others

There is no 3rd subclass. That extra spot is used for when you lock in one subclass, you get a copy of it that levels up slightly faster

First of all the Hunter is worthless I'm raids. Blade dancer will only allow you to take out large groups of trash mobs. An AoE grenade can do that same job. The golden gun can only weaken a high priority target, then I found out a head shot with a sniper does more damage than a single shot from the golden gun. The Hunter is the most complicated and useless class there is when it comes to raiding. And every class is dps. I can be a sun singer lock and still do as much damage as a striker titan. Your entire argument is invalid sir.

Sunsinger is more of a DPS subclass than Bladedancer or Gunslinger mainly because of it's DoTs, the ability to carry 2 grenades and the fact that Radiance boosts all of your abilities and not just your melee or gun damage for a short time. Essentially you will be able to throw down like 5 or 6 grenades while Radiance is active (double that if you gift of the sun.), Melee is one-hit on most enemies, Or if you want a DoT spec running Viking Funeral will ignite any enemy that is damaged by one of your abilities. We also don't know if Radiance will boost weapon speed, Gun damage, or movement speed while under the effects either, but it seems unlikely. Bladedancer and Gunslinger are more of burst damage subclass. Also getting into melee range of a boss has proven to be a bad idea, based on the Alpha and Beta. I honestly don't see Hunters being very useful in Raids. The only real thing I can see them being useful for, is clearing trash mobs with blade dancer, and possible generating a lot of orbs for the team and that's about it. Not saying they won't be able to do it, but stacking the team with Defenders, Sunsingers, Voidwalkers, or Strikers might be a better solution. My ideal Raid composition would probably look something like this: Striker Defender Sunsinger 2 Void Walkers Bladedancer. The Strikers and Voidwalkers would be great at crowd control and also be able to do heavy damage on trash mobs. A Sunsinger with song of flame would reduce all cooldowns of the fireteam, and also be able deal high dps across many different types of enemies, while the Defender would put up a shield to draw aggro or if someone needed to recover. Depending on the how the Defender specs, they could also buff the fireteams weapon damage or give them even further damage resistance while also generating even more orbs for the fireteam. Suppressor grenade is also capable of preventing enemies from using abilities for a short time which sounds amazing when used against a boss. Combine that with the Sunsinger's Song of flame, and the Defender can keep spamming grenades on the boss, preventing him from using abilities. (Defender and Sunsinger are sounding like the most important roles in the Raid atm.) Bladedancer could come into play by clearing trash mobs whilst taking minimal damage because he/she would be invisible and generating orbs for the fireteam whenever Arc Blade is up. Not bashing Hunters, but to me they seem very inconsistent and don't really seem to benefit the team in any way. You say they are high dps, but I'd much rather take a Sunsinger who can deal just as much DPS, if not more, because of his abilities to reduce cooldowns, lay down DoTs on a ton of the enemies, and because he's just more tanky than the Bladedancer. Plus who knows Song of Flame could stack with Radiance resulting in even FURTHER reduced cooldowns for the Warlock's grenades. Hate to break it to ya, but Hunters are looking more and more like a PVP class everyday.
