What you wrote about Tactician in DOS sounds not awfully bad, more or less I already created my party this way, except crafting which I never did in the EA.
What I wrote about reloading, I don't like it as "the general tactic", so that you cannot normally win the first time because you inevitably have to know certain things you only can get from the fight. That reminds me to MMO boss fights which I always hated.
Of course in some fights it is ok. I lost some fights in the EA, one against the crocodiles, the frogs, the magical skeletons in Withermore's tomb, and two of five against Radeka. You learn and try to do better. All is in the dose, let's wait and see. I will give Tactician at least a try.
