So, I got my rogue to level 110 and thought I needed to learn my rotation. Hour n a half on the dummy and I'm pulling within 5% of my Simmed dps. Now I'm ilvl 858 and regularly dps around 300k.
For tanking I just practiced in Heroics - they may have hit softer, but I could practice rotation my CDs as they came up to smooth out damage income as much as possible. Once I hopped into heroic raids I found those skills transfered fairly well.
And then...there's healing. I simmed myself out and it gave me an absolutely ludicrous number - 490k HPS at ilvl 830. I followed it's suggested 'rotation' on the 3 heal dummies in the druid area and found I was regularly pulling 330-400k HPS, but those numbers are completely meaningless in practice. I tried jumping into LFR but I honestly feel like 1 healer could solo heal that with everyone ignoring the mechanics and still find themselves very bored. I hopped into a normal raid but again - simply nothing to heal. I'll likely be coming to my guild run next week as a healer and I have almost zero confidence.
What's a good way to practice raid healing? I don't want to hold my guild back from being out of practice, but everything that I can do seems pointless. :/
