Give other classes more place in DOA?

I guess Warrior, elementalists and monks are too useful in DOA, other classes just isn't as important as them, what do you guys think?

yup
(is glad when there's a simple answer he can give to help folks)

caveat: sometimes if you go with friends and guildies they can overlook other classes weaknesses for filling a specific role.

Wrong.
The other classes can be quite useful in the DOA. It's simply that the cookie cutter build is based upon those three, driving the community into thinking those would be the only viable options for DOA. Sort of like, for example, everyone thinking you absolutely NEED Trappers for Urgoz while in fact you're better off without them.
The teams in DOA would have it a lot easier if only they could break their Trinity thinking. Which they sadly can't because they mistake the trinity for elite.

The typical build runs with warrior, monk, ele, necro. The trapper build uses ranger. Funny how it's usually the core classes that become the popular farming meta...

^^ /sarcasm sorry I was too subtle
other classes *can* be very good there, but trying to find a pug with one is still gonna be a problem.

Any class can make their way in the DoA... there no real point to this.

You don't even need a PuG... just level up your heros and your do fine.
