Summoner doesn't feel like it Summons.

Even that isn't much of an issue since you hardcast the first and then swiftcast the other one. Comes out real smooth. Just like Ruin/Tridisaster > Titan Spell > Mountain Buster are also butter smooth.

Garuda you can do whatever you want. Not sure if it's beneficial to do Ruin/AoE every 2 casts of a Garuda spell.

I've been swiftcasting Garuda's Astral Flow ability (can't remember the name) since it has such a long cast and feels like its bringing my momentum to a halt when I try to hard cast it.
