Just a few in-game suggestions, is this the right forum?

with currency, Hold LMB+Shift for multi-item crafting.
Instead of spam clicking, hold LMB and drag cursor over multiple items for speed, accuracy, and efficiency. If you ID everything, save up 20 stellar amulets and heavy belts like I do this would be big.

For the several mob and boss abilities that can 1shot with only a .25sec response time there should be more than just offensive abilities.
I think the game would be much more enjoyable if it included several defensive cooldowns such as interrupt, damage reductions, +armor/resist, invisibility, absorbs, reflects, life/mana leech, +max health/mana, AOE stun, AOE slow. On yourself or an ally there are many different ways that each of these could be applied.
Came from a game that I had over 30 keybinds and this game you can get away with just a couple. Teleporting around, 1 shotting the whole map is boring.

Go subscription based and Introduce an auction house with well integrated item stat search and price checking functionality for subscribers. Also introduce several quality of life improvements to subscribers such as currency tab access while subscribed. Unsubscribed will be able to withdraw from tab but not deposit. So still worth having the option to buy tabs.
