I still think that "aspect warrior" will be a class on its own, or split into two variants. There are far to many aspects, which are far to specialized, to be their own classes. More likely, you will take on the roles of the various aspects by equipping their gear.

Autarchs are technically specialised in every single last one of'em. Be it so they change the armor and change classes. Simple as that no? That's just me though.

yes. someone with sence. also:

dark reapers- long range, stay in one spot for most of the battle

fire dragons- short distence, hopiing in and out of vehicles to get around the battle

Sigh... thats why I said they are "similar" not "identical" ^^;
Dark Reapers are amazing vs. heavy infantry and hero type units, while Fire Dragons with their melta can also rip them to shreads. Dark Reapers get an AV weapon also (Starshot Missle) btw ^^; Hence their role a bit similar. And yea, from different range =)

Actually, the devs will have a hard time with chosing between the aspects, since all have their role in combat and each is amazing on its own right.

Ah I'd quite like Scorpions for stealth, melee, tankiness

Maybe Banshees too I wouldn't care/ a female only melee option, debuff and fast

Reapers I'd like because they do TONS of dmg

As a jump unit I think Spiders would be awesome for melee or ranged

Definitely need a Psyker that plays into Warlock or Farseer

I like this idea though: Aspect warriors This class might be divided into Melee Aspect Warriors and Ranged Aspect Warriors.

So that would open the Guardian option as well for jet-bikes, vehicles and mobile turrets.

The problem is that Dark Reapers are not effective against vehicles. Their guns fire barrages of tiny missiles that can completely destroy a Space Marine but are not effective against anything bigger than a Sentinel. This makes them ill-fit for long-range anti-tank support.

Fire Dragons have very powerful guns but they need to be VERY close for them to work and I can imagine them to have a limited rate of fire. This again makes them ill-fit for fire support.

The solution? Don't fix it. Have long-range vehicle fire be a counter to the Eldar infantry. Force them to use vehicles against other vehicles.

won't matter if we can use most aspect warriors

Otherwise
Anti vehicle: spiders, scorpions + your own vehicles

I'm guessing that we'll see :

1. Dire Avengers - the rank and file troopers.
2. Striking Scorpions - sturdy melee specialists.
3. Warlocks - support/damage hybrids.
4. Fire Dragons - vehicle hunters; they could use Fire Pikes if their limited effective range will be a problem.
5. Swooping Hawks - mobile hit-and-run specialists.

That'd make for a quite balanced force, not to mention one with a very iconic look.

And I'm assuming they will most likely allow us to use Exarch gear, even if we won't be able to play as such. That'd solve a lot of flexibility problems.

A very good suggestion; certainly more interesting than having Aspect Warriors being simply an ordinary set of classes.

As interesting as it may be, however, there is a slight flaw; it would be a poor representation of the lore if one could just see a tank on the battlefield, quickly fast travel to some base, change one's gear (and thus aspect) go back, destroy the tank and doing the same with every other threat you see. In short, I do not wish to see this implemented in a way that is more akin to changing one's set of weaponry as opposed to completely new Aspect Shrine.

Perhaps, if you could do it only once per campaign (campaigns being three-months long, in case someone here did not remember/didn't know) it would make sense. THEN it would be perfect.

I don't think that the aspects should be based on gear, but rather the skill tree that you choose. And after that comes the gear. It would add a more permanent choice of aspect.
