General Feedback

For endgame mapping
1 Just make each map have six portals/tries. This will also stop people from losing valuable drops if they die before they can pick up their items. Hardcore mode exists for a reason right? Making each map have a boss makes this a much bigger issue going forward.
2 The experience penalty is just tedious and needs to go
3 Removing the need to do tower setups is a big improvement. Just don't nerf drops because removing a tedious process is not a buff for players. It simply stops wasting players' time and nothing else. Haven't played the latest patch so I don't know if this is relevant or not.
4 don't reduce monster density for the open area maps. High density is what made those maps the best maps. Especially for mechanics like ritual.
5 Also for ritual losing a ritual when you die is a severe penalty for mechanic that is very rippy until your character is very strong.
6 bring back icons for rare enemies and have icons for ritual and expedition because finding the last ritual especially is a tedious process.

Trials of Chaos
This is easily the worst content in the game.
1 The bird boss is pretty badly designed. Too many rippy mechanics that are just too fast. Player movement speed is just not high enough to handle the mechanics. Also some mechanics are extremely hard to see.
2 The escort mission and 90 second rooms are total sleep inducers. They need to go or be changed
3 rewards are reelly bad. The only high value drop is the unique jewel but the boss requires 3 keys to enter.
4 some choices are not really an option and guarantee a failed run. The shade, petrification statues and Volatile Fiends in my experience.

Trials of Sekhemas
1 the floor 2 hourglass is still bugged. Rares don't spawn
2 make gold spectrum chests in the treasure room stand out more.

Pinnacle content
1 Not a fan of 1 try even though the bosses are easy once you have a strong character. Again hardcore mode exists for a reason right?
2 Runic shards for Olroth might be a bit too rare

General
1 gold fee for divine to exalt trading is simply way too high.
2 for controller the merchant tabs should be more like the stash tabs. Have them all listed on the side at all times. Instead of nested in folders. Or have an option for this.
3 tablet stash if tablets are going to be around or fragments stash tab. Stash management is quite good now even on controller.
4 Scrolls of wisdom are a really bad design choice. buying scrolls is pure tedium. Maybe have one scroll of wisdom with infinite uses. Friction for the sake of friction is not good. MAybe slot it in along with equipment.
5 Allow alcehmy orbs to be used on strongboxes. This will free up a lot of character inventory space. Maybe this is already possible. Haven't played the latest patch.
6 bring mirror shards into the game as a way to store currency if people want to take a break from the game. Maybe this is not in your interests. But it would be good for players.
