Hmm, it does not sound like a game for me. I didn't even play MMX yet (and I probably will not). I don't like when I cannot move individual party members during combat and when movement is not a tactic (I enjoy putting my rogue behind enemies in IWDEE to get a backstab).
While you can't move around in a map, positioning can have a big factor in the game.
I think it's like
5 slots for enemies in the back
5 slots for enemies in the front
4 slots for your party in the front
4 slots for your party in the back
Now a paladin only buffs the people directly surrounding him. So it's important to cluster together for a buff.
There are spells which target one enemy and the enemy infront of him.
Also if one enemy or party member of a front row is slain, the member behind him will immediately move to the front. Which is something to watch out for in your party, and something you can take advantage of at your opponents.
In addition the very left of your guys will not be able to attack and be attacked by the very right of your enemy for example.
The Back Row can only attack the front row of opponents when a Pole Arm is used.
If you use a bow however you can target all enemies.
And then there is the summoner who can conjure 2 additional members which will fill the 2 remaining slots.
So you can't move around freely like in a BG or Divinity or so. But positioning is definitely a relevant part of the combat.
