Army composition question

[carlec]

How do you know when to get rid of a unit and move on to some other unit? I mean, at times it is easy to see that a stronger unit (say, Ancient Bears to Bears) just makes sense, but at other times, it doesn't, at least not to me.

So, right now I have both Priests and Archmages (I'm a Paladin). I can start, now to get Inquisators. Do I drop the Archmages or Priests for them? They don't seem to do the same kind of attack, so I can't really tell. Adding to the challenge is that I seem to be out of Archmages, at least for now.

I am level 11 (I think) and am just now getting to the mines. I have only done a few quests on the Islands and most armies there remain stronger than mine.

My current army is:
Bowmen (109)
Royal Snakes (7
Priests (105)
Archmages (27--but I only currently have 6 or 7)
Ancient Bears (5

I think its time to get something new, but there are no horsemen so far, only a few knights and, well, I'm just not really sure what to upgrade or move on.

Ideas?

I'd drop your archmages for inquisitors (for the resurrect and rage/bless)
and replace the bears with griffins (for flying to grab goodies, speed, and multi retaliations)
and replace priests with shamans (for totems as distractions plus healing)

I would love to have griffins, but can't find how to get them. I found the island, and hoped I could get them to join me, but they wouldn't. I am guessing that I have to finish the quest of the griffin king, but that is still beyond me right now.

And I haven't seen Shamens yet. Are they with the elves?

Are skeleton archers really the best as everyone says? I was not going to go down the undead path with this army/game. This is my first, so I was hoping to add elves, but certainly haven't found them yet.

Yep, you have to finish the griffon king's quest first. It's worth it!

You can get shamans from the castle where the orcs are on the first island, but you have to beat them in battle first.
