First things first: I'm a resto druid and I love the current "hard style" healing, but there is a "but" that I wanted to address: interrupts. Rather the lack of using it.
I felt this in heroics first when healer/caster mobs are just being ignored and I have to suck up all my mana to keep the ball rolling. The worst feeling is that I can do nothing about it (heroics can have posibilities with cyclone: true)...
Then I started raiding and I ended up at the Omnitron Defence System with our lovely Arcanotron. All I ended up with, is seeing the raid being wiped because it's just impossible to heal up the damage if the interrupts are lacking. After endless tries of making the dps interrupt all the time even at the cost of losing some dps, no real chance has come.
It's so frustrating because I feel so powerless against this. The DPS doesn't seem to get the fact that it's so ridiculously important to interrupt.
So I want to call upon all you DPS'ers who look at their own dps first before the general success of any fight. There is a very good reason we, mostly healers, say to interrupt all the time. Just try to listen to us, because I'm sure most healers want nothing more than you guys being alive and kicking!
Take your responsibility and use what is given to you for everyone's sake!
PS: even interrupts with a long cooldown are no reason at all to not use them...
