Vaaltempel are horrible

Roomplacement:
There is no Indicator in which room can be expanded on and which cannot.
Some rooms allow you to branch of with some rooms but you only get the information through the tile you currently have.
-> why no suptext to the room that says you can place room "xyz" next to this tile
or am I missing something

Roomlayout and mob density:
Playing a melee character I seem to die regulary in certain rooms because there are just too many of the first shoot lightning ball than lighting line through the ball guys. especially since the room they are in is way to small and you cant evade because I get swarmed by other mobs in the room.
While having a ranged attack you can cheese it through lobbing attacks into the room from the other room, but that isn't fun...

Loot:
Yeah you need to bring your loot that you want to enhance into the tempel and the tempel gives you more loot. But I Have less space in my bag since I need to cary my loot that I want to use the workbenches on through the level too...
Just finished a tempel with the thought ok then I'll enter it again and grab the loot that is lying around after selling...
Well the Tempel closed on me, pretty sure that I was able to go back into the tempel before, probably haven't finished that one before completly, so in future I need to leave one room untouched, haul the loot back out of the temple and then do the last room because the temple vanishes after the last room is complete?

Vendors infront of the tempel:
Why are they not in the tempel? It is nice that they are close at hand, but why aren't they in the tempel itself? When they are able to haul my chest and themself to a place that I can only acces through going through a wierd portal then they can come with me into the tempel too, from the looks of it they are supposed to be accesible but why this extra step?

accessing special tiles:
don't know how many runs it is supposed to take, but all the tiles that I unlocked through the architeckt are in the top left corner, and I dont get the road parts that get me there, with 1-2 roads in each cycle the inability to turn them and the limitation of how one is able to place them it doesn't feel great...


First I had fun with building a dungeon and puzzling pieces together so I can get higher tier rooms, just to realize that through upgrading the rooms I locked myself out of getting to the new rooms that spawned on the map.
First the rooms felt way to easy I was just blazing through them, hoping that they would get more difficult later on... Now at a higher level I got what I hoped for and more, sadly, I die so often that it isn't even funny anymore, blocked into places with no room to roll, staggered, sniped, puddled...

Ah and another one why the heck am I sometimes able to get back to the portal through which I have entered the tempel and sometimes I need to take the waypoint to get to another waypoint to run back to where I was before?

I really want to like the mechanic, but currently it isn't fun at least for me :(

Edit: On a further note, why are they even here? This is early access, why waste development power on something that may be forever gone after the league expires instead of patching the game and filling up the skill and character options, that are going to stay?

Edit2: Running tempel in multiplayer isn't rewarding at all, since only the guy that opened the tempel can actually use the stuff in it and it already bugged out once when none of my 3 person team could interact with workbenches or even the leavers for the treasure chamber so we ran the thing for some loot that we sold 100% of since none of it was usable not being able to interact with any official reward.
