About the witch hunter's professional sublimation talent-Sorcery Ward

After tough battles, I finally got the Sorcery Ward after completing the the 4th trial.
My few questions:
1. How to achieve its quality effect?
2. The definition of the Sorcery Ward is effective against elemental damage. However, after testing, it was found that it is ineffective against damage of the ignited ground. Shouldn't the ignited ground also be elemental damage?
3. Compared with the difficulty of obtaining it, the effect of the Sorcery Ward is very useless. After many battles, I found that there are not many scenarios where it is effective and it reduces my armour and evasion. As a result, the survival rate of the witch hunter has not been improved.It is recommended that it also be effective against chaos damage.

1.The quality of Ascendancy skills can't be increased for now. They probably designed it this way because they plan to introduce a unique item or mechanic to enhance it in the future.

2.Sorcery Ward only applies to hits, so it doesn't protect you from ignited ground.

3.I've been using it with a mace and shield Witchhunter and I don't think it's bad, I feel pretty tanky. You lose a lot of defenses, but you can reach 10k Elemental Shield, which is quite good. Most enemies, especially uber bosses, deal elemental damage hits.

I would buff Witchhunter, though. I think 50% less armor is a little too much, the corpse explosion chance is too low, and the node that grants points for the secondary weapon should also provide weapon swap speed.
