Sch Seeking Advice for t9

[Beyondgrave]

So my group been working on t9 for the last 2/3 weeks and we seem to be struggling quite a bit. Our dps is a lil on the low side, getting 6 meteors normally. But that's the dps issue, mine is dealing with the ravensbeak and it dots. I remember when the first and 2nd ravensbeak will be coming out but not any after. Also, I normally have to do a countdown I my head for when the dot will explode but id sometime lose track due to dealing with the other mechanics and micro managing Eos. Lots of time, I would cast Aldo as soon as I see ravensbeak start, but normally, the cast will go off too late. I tried virus once the cast start but it doesn't seem to have an effect. The thing that kills our tank the most in p1 is the ravensbeak dot. Does sacred soil work for the dot? Also, any additional advice is appreciated.
