Hi, i just wanted to give my feedback, i am much older then most here, lived on this planet for over 4 decades now, seen all the games, good, bad and ugly, but this is truly worst game i have ever played.
So you have lived about as long as I have been involved in computer gaming, welcome youngster

If this is the worst game you have ever played then there are many games you have not played. It is not the best ever, but not even close to the worst ever.
I always play as a caster and caster concept in this game is beyond broken. Who came up with the idea that caster should not be able to cast spells? Seriously?! After you cast spell you need to go to camp EVERY GOD DAMN TIME!!!! WHY!!!!!!!!!????????????
As noted it seems you have not played as many games as you think. This has been a DnD game mechanic since the beginning so nothing really new. In fact in earlier versions we did not have the cantrips we have today to fall back on give a caster offensive potential.
Casters have always been limited, especially early game because by later game they can be god like. To be an effective caster for DnD you need to make sure you have access to scrolls and learn not to jump into every fight throwing spells. Let your warriors do their thing, many fights they can get through fine with you supporting with cantrips. If things are close or getting really scary then you wade in with your spells.
This is not an issue of a bad game, but rather of bad game play and not understanding the system.
