Zero co-op synergy?

[Raim]

The heal from Paladin seems like the only thing in the entire game that benefits allies. Not a single one of the specializations gives buffs or heals for other players or even their own summons or NPC companions. Why is Haste not an AoE for example? At the very least when/if new classes like Priest get added they need more group support options even if its just a specialization.

Edit: After playing Warlock more I was wrong about them at least, they have some good group benefits.

Paladin and Warrior both have symbiotic skills. Don't forget shout passing on buffs to friends within their area of effect.

Warlock has a damage mitigation field around them which would... benefit a paly or warrior tanking for them as it so very well happens.

Casters using Ice based weapons as well as the traps born from archers would allow for crowd control and easier kiting with their snaring effects.

Its not like their is a bard class that can't do anything by itself that makes someone else really good but their are synergies if you look for them and they are quite useful.

People forget there is more to co-op than giving out buffs, there are strategies that involve cooperation between people. If you and a buddy work together to lift a tree log, you aren't inputting your chakra in to them to make them strong, you each individually put forth effort to complete a task. Use your head to think of ways to complement tactics or skills rather than looking for a buff that says "make friend stronger".

The Warlock gets a boon for their Dark Ritual that allows it to leech life for all party members within the circle.

That said, I think there are a few things that are in need of a balance patch, for one the Dark Ritual cannot damage stationary enemies like the Elemental Totem or Poisonous Plants (Which, also makes the first boss an absolute PITA)

I also notice that the enemy density is much higher when you have 2 or more players in your party, so it's give and take.
