I'll give you hurlocks and genlocks, essentially large and small grunts, no variety there -
Without a combat log its difficult to gauge the percentage of opponents you face. I'd lump them into the following categories, to which I have added my
vague guesses as to what percentage of the monsters you face in the game.
1. Basic Enemy (about 66%)
Genlocks, Hurlocks, Dwarves, Elves, Humans, Skeletons, Shrieks, Ghosts, Wyrmlings, Deepstalkers, Revenants (even though they are cool because they are so tough), Brontos, Abominations, Non-spellcasting Demons
2. Basic Enemy Archer (about 15%)
Genlocks, Hurlocks, Dwarves, Elves, Humans, Skeletons.
3. Spellcasters (about 10%)Emissaries, Mages, Spellcasting Demons
4. Beasts with Overwhelm (about 4%)Mabari, Wolves, Bears, Spiders (IIRC), Drakes, Werewolves
5. Large Monsters with knockdown and ranged attack (about 4%)
Golems, Wyld Sylvans, Dragons, Ogres
6. Assassins (seen about 4-5 times in the whole game; about 0.5%)
Various races.
7. Big Bosses (about 0.5%)
High Dragons, Broodmother
Apart from the big bosses, and probably, "kill the mages first", theres no real difference in how you approach combat with virtually all the monsters in the game.
but at least from what I have seen, Spiders, Ogres, Shreks, Emissaries, Wolves, Assasains, Mabaris, etc. all have distinctive attacks as far has who they target and how
.
See above.
I recall seeing an area in Orzammar where Spiders and Darkspawn were attacking each other... you could certainly play that several different ways - charge in and get aggro from both parties, wait until one side or another has an advantage and go after the weaker... whatever you like.
One instance in the game.
I would think there is going to be an optimum mix of party, equipment, and tactics that will give you the best overall chances of winning an encounter - but even at that you can't really say that you would approach every battle with the same tactics and expect the same results...
My point is, when you have those optimum tactics (and these can be really simple), you never need to change them. What works good enough in one battle will work good enough the next hundred battles. You never really need to change your tactics, because the monsters never force you to change your tactics.
