This game has the exact same problem as DoS1 did, it starts out great with some challanging fights (like crocs and arena) then the game gets easier and easier until you get to around lvl 15 where it more or less turns into a very slowed paced diablo game where combat is just you pressing one or two skills then moving on to loot and repeat. I had to start over at lvl 15 in DoS1 because it was no longer fun and i have now started over in DoS2 on lvl 15. Never finished the first game for this reason and i might not finish this one either for the very same reason. Tried an honour mode run in DoS1 only to be wiped by a stupid lava trap statue even tho the lava didn't even touch my feet.
So in short, Tactician is challanging the first 4 lvls, honour mode is not an additional difficulty or challange its just a way to piss you off because of stupid OHK traps. As good as this game is and as good as DoS1 is they both have one of the worst progression ever.
