I do find it annoying that there are so many Concentration spells and cantrips for Clerics (Guidance and Resistance cantrips could have been "one active per person" instead), but I prefer to encourage Larian to follow the 5e rules. That is only my individual feedback and I will accept whatever Larian goes for, but I do care that Wizards of the Coast (WotC) did a lot of playtesting before and closely monitored feedback for years now, for the most popular edition of D&D ever. And WotC does not allow many video game companies to use their license, IP, or rules. You might as well do 5e with as much fidelity as possible, with some fun tweaks nonetheless (like the weapon special maneuvers are a fun addition that maybe 5e should add).
( again, that is just my individual preference or view : no problem )
( for fun, Concentration was invented mostly after the new edition removed the possibility of casters being interrupted in their casting, which was a radical change from past editions.)
That's my position as well. Even if you find fault with 5th ed it should be implemented as WotC intended.
I think when the game moved to 2nd edition there was a backlash against powerful magic items and the conversations about "too many magic items" is an artifact of that move. The 3.75 ideal is "just as powerful naked".
But well designed magic items allow players break the rules without breaking the entire ruleset. If you want to concentrate on two spells at time then find the bracers of the divided mind. Think missing is boring? Let the players get their hands on +2 sword and you will be able to hit something without instituting something like AC reduction / HP bloat.
I mean if we can make reference to the 4th edition heresy we can also pull things from 1st and 2nd
