Specific issues you had with Hexen

[Viscra Maelstrom]

Heretic is fighting armies of monsters with weak weapons.

The weapons are fine, the monsters have higher HP and pain resistance than Doom ones.

and there's the inventory system, too. the time bombs are great for thinning out crowds, the morph ovum turns dangerous enemies into harmless chickens, the quartz flasks are portable medikits and the tome of power is for when you can kill a lot of things fast. basically, Heretic's a bit more about the utility of the resources you have than the firepower of your weapons alone.

the time bombs are great

the door is right over there, please use it.

(I always thought that some kind of tripmine would be worlds better.)

I replaced the mage's flechetts with trip mines and they are so much more use full and play into the mages "deal damage from a safe distance" thing.

The time bombs aren't really strong either, or their explosion radius is lower than I would expect. If perfectly positioned, it almost kills sabreclaws; it only takes 1-2 hits from the wand to finish them off.
