Subclasses for DA4

Classes have been discussed a lot, and there're people who suggested having more classes even, or going the Andromeda approach of "everyone can be everything" which I personally wouldn't enjoy, but I'd like to take a middle ground approach.

Here's the thing, Dragon Age already has subclasses of sort, it was just never properly developed.
Take the Rogue, they can be dual dagger or archers. Warriors can wield shield+sword or greatweapons. They are still essentially rogues and warriors, but they have a little twist. I compare them to the advanced classes in SWTOR, in which you are still whichever class you choose at core, but slightly different.

Say, Rogues they could specialize as dagger or archery, still sneaky. With one or a few more skill trees depending which one you choose, passive and active skills. Archers would focus on ranged combat, while dagger users would specialize on criticals, ignoring armor perhaps at some degree, think about hitting critical unprotected spots (eyes, neck, joints, weak spots etc). Blocking would be jackshit, due to daggers being too short to properly block other attacks.

Warriors could be shield and sword, dual sword or greatweapons. The idea is that the guy with shield+sword has pretty good missile protection (arrows/bolts, and magic projectiles to a small degree), good defense skill (if you do block properly using an actual button for blocking), but wont be super effective at dealing the best DPS possible. Dual sword would be spectacular for DPS, but wont be able to block any type of missiles, blocking skill could still be decent because you have at least one sword in hand. Greatweapons could deal massive armor piercing damage, great to take out bosses and the likes, blocking ability would be somewhat poor.

Mages could have a support subclass that would focus on aiding the party more than actually doing the killing, here you will also have your healer. I suggested on another thread that mages could choose not to use any weapons at all while casting spells, this will give you lots of speed, but spells will suffer a damage output penalty. The idea would be perhaps dealing with lots of weak enemies pretty quickly at the cost of loosing raw damage.
Wands could be another weapon type, so long as they give them cool looking animations and not the "point and shoot" one.

The idea is to give subclasses the base set of skills, but depending which sub, they'll get a few more new set of skills based on weapon choice and other things.

And then you could have pseudo-cross classes. This idea is kind of borrowed from Path of Exile in which you have cross-classes that share things of two and even three classes at once.
First thing to come to mind is the spellsword. Someone who uses a sword, but cast spells also. Of course their repertoire of spells would be different and more limited than pure mages, but with that and their swords they'd make do.

Lastly, and a bit unrelated: bring back crossbows. No longer a signature weapon of a friendly dwarf. Crossbows should be a weapon type again, and here's an idea.
Let everyone be able to use one, rogues, warriors, mages if they want. Why? because of the nature of crossbows, they were created because they require no skill to shoot, unlike bows that require a strong arm and years of training. What's the catch? shit reload time and crap range. So you cannot use that thing all the time if you specialized in the warrior's path, for instance.
What's the point of letting everyone use one? because why not. Get one free shot and then take out your sword and continue the battle normally.
I think there should be a special skill tree. With actual training you could be even more effective, better reload speeds, better accuracy. Not sure if making it a tree for everyone or just for rogues though.
Crossbows would deal pretty good damage, but the reload and shorter than bow range would be the balance here, without proper skill investment it wouldn't be viable to keep firing bolts as a warrior instead of just good old slash and stabby with your sword.
This idea came from Origins, you could equip a secondary weapon in that one (I think also in DA2, but there were no crossbows there), and everyone could use a crossbow too if memory serves.

Anyways, that's some of my ideas for hypothetical subclasses.
