It's just combat we're talking about here, but still. You really should read the OP if you're interested, it's much better than what I have written here. 
No one has to take on specific roles (healer, tank, etc.) because of the class verasility, every class can do every play style. Everyone has to bring a healing skill, which means everyone have a fair chance of healing themselves. And since everyone can revive eachother, combat doesn't stall because you're downed, as you can quickly get back up into the fight.
Buffs in GW2 are called boons. None of these boons stack in effect, but if you buff someone with a boon they already have, the time is added to it so it lasts longer, instead of your buff just being wasted. And there are no skills that target allies, so you have to watch your allies more carefully, so you can move in and protect them when they need it.
Skills are also useful in many situations. A skill like Wall of Deflection, can be used to defend allies when retreating, or push into enemy lines, not to mention for countering a strong enemy attack if cast right. There is more focus on players being able to move around and physically finding cover.
