If you are a DPS, on a boss where you don’t dispel and just kill, then the meters are a very good indication of how you are doing. Gear and class are of course factors, but you can directly compare yourself to similar people on the same fight. You can get a good idea of how well you’re pressing your buttons.
Healing is a little more complicated. Unlike a boss that you can do unlimited damage to until it dies, there is always a limited amount of healing that can be done. You can’t heal for more damage than people take. So, the same player with the same gear placed in a different raid might have very different numbers. Healing numbers are the highest when you have a raid that takes a lot of damage, but not so much damage they die. And in a raid that runs a lower number of healers. If you’re in an MC group that thinks they need 10 healers, your numbers will be less than one with 8 healers. It also depends who you are healing with. If a few of your healers are slacking or just not very good your numbers will be higher.
That being said numbers are still important. Here is what to look for:
1.) Comparative healing – you can look at your healing within your raid and see if someone really isn’t trying much, or making poor choices, and healing very little. Particularly in long fights or if people are dying.
2.) What are they casting?- If another druid is doing much better than you and their gear is similar, have a look at what they are (or aren’t) casting, and when. This may give you an idea of how to improve.
3.) Dispels – Very easy to pick out the slackers here
4.) Don’t look at over healing – That is some stupid outdated uselessness. Long ago when very early meters counted over heal as healing numbers people cared. They haven’t for a long time. If you aren’t OOM (out of mana) and people aren’t dying this number means nothing. You’re a druid, you’ll have overheal with HoT ticks. If your raid leader pretends like it this number matters, they don’t really get it. If you are OOM… well then maybe have a look.
Of course all healers are all on the same team, and trying to achieve the same objective. And in the end, killing the boss is the most important thing. But a little healthy competition between healers can make everyone better. As long as it’s friendly and doesn’t cause you to make bad choices 🙂
