"Sorry if I sound rude, but from what I am reading, you don't come over as an experienced player in any way. At the very least not experienced with CRPGs, maybe MMOs?"
You sound more like you didn't understand what I wrote.
"1. The way itemization goes in DnD, it is your gear, that really makes you powerful. As in real life, you stick a long time with what you have. Later on the itemization becomes a problem, because you get ridiculously powerful. Apart from that you can get some pretty amazing gear in act 1, if you are actually thorough, like the Blood of Lathander, Aluvae, Light of Creation, Spellsparker and so on."
I won't be arguing about that. I have omited only one side-plot from act 1 which was the cave from the well - the spiders were too powerful for me at that time. There was really nothing left in act one so... or we played different games or you are boasting too much.
"2. Character development depends a lot on your class, some are outright boring (which is not the same es weak), others offer stuff at pretty much every level and you have multiclassing, which is absolutely bonkers in this game. Dare I suggest investing more time in game mechanics and less in looting vases? Games like BG3 life from experimenting and respeccing is very, very cheap."
Don't agree. I had two figters, a mage and a rouge in my team. All of them had poor features at leveling up and all of them got only some hit points at some levels. Compare this with what you could have in Swoard Coast Legends.
"3. If anything the game is to easy. The battle you are mentioning is kinda annoying, but it is over in a few turns, "
If you ended the batle with Yurgir in "a few turns" you are definitely confabulating. There are plenty of topics in the net with people complaining about this boss and the fight. I killed it only because I've red some tips from the net about throwing at him a gas bomb - which is not logical in any way.
Off course you can make the fight a lot easer by talking the boss to kill his minions but the plea stands.
