Testing out classes is surely not a reason to replay. You already play 4 classes and learn 80% of the abilities in the game. Why on earth would you play it for the 3rd time, if you actually know the potential of your heroes?
Surely you jest. There is a difference between knowing what skills are available, and building a character around only using a certain subset of Abilities, Skills and Talents. This game allows you to build your character in many combinations.
For example, in D:OS 1, before the EE existed,
I decided to make a "Speed Mage" build, a Mage built around splitting their stats between INT and SPD, and using touch-range spells only combined with Far Out Man. All the components were there, but few to no people put them together in that way. I called it the "Inquisitor". That preset got added to the EE.
I'm already planning to adapt the existing Inquisitor class in the game to make them built around gaining extra AP in combat, which means taking the Elf Race, and the skills Haste and Adrenaline Rush, as well as the Talent Warlord. A game like this can always have interesting things for players to discover and/or try out.
There always should be either a good story, or an ability to grow powerful enough to win fights in seconds. I forgot to mention one import detail: in both RoM and SR your final boss would be tough as f* even if you have the best possible loot on your heroes. That is what both DOS1 and DOS2 missed (can't be sure about recent patch). But common monster would be very easy (that's minimising the routine).
You are completely missing the central idea behind the game's combat. Combat in this game is not supposed to be routine and easy. There are no respawning enemies, no grinding for XP. Each fight has to be interesting in its own way. A game with no respawns and enemies who are easy and boring to kill makes for a boring game.
You are absolutely not supposed to be able to grind to make combat easy and boring.
You can't test a different class when items do not vary much. There are not many fights in the game, so you can't place too many unique items. They should be present, for sure, but they should be really cool so that you don't sell it to a first merchant. A wand with 4-5 poison damage and no enchantments. Wooow...
It's something you get at level 1 or level 2. Sorry that it isn't fancy enough for you. It's not supposed to be a legendary weapon of the famous evil king. (You get those later on the island.)
