As someone who also lives in Australia and can solo heal titan HM as a scholar I will echo these:

1) Memorize his rotations. This will make your precasts better and let you 'count' down to his abilities (WoL).

2) Use legacy control settings- this will make dodging a lot easier.

3) If you have to pick between finishing a cast and dodging always pick dodging. You have lustrate and you shouldn't be afraid to use it.

4) Mute the games music. This will make focusing easier.

5) learn to control eos if you have problems with heals

and 6) Practice, practice practice
