Our entire army is like how you described it, Mortim...
People are like "demigryphs should cost 60 points", but why they can't accomplish anything. S5 is sad, elf infantry has better S...
Same thing with greatswords, give them ASF and I6, voila, completely broken unit...
Whenever I talk about how chaos is wayyyyy more powerful than empire and elves are above even that, everyone just answers with "Well chaos & elf models cost far more points per model! This makes it balanced!" So, if you think like this, that also means that if the points are equal, the units are balanced. Lets do a little comparison, compare Chaos warriors and halberdiers, both worth say 250 points.
So were gonna equip the warriors with the following :
Chaos warrior - 19 points
mark of nurgle
Halberds
And compare to our 6 point halberdiers.
250 points gets the empire roughly 42 halberdiers.
250 points gets the woc roughly 13 warriors.
So lets compare them in combat :
Consider the warriors are 6x2 with one extra guy in the back, therefore getting 18 attacks.
They strike at I5, meaning they go first. WS5 versus WS3, the warriors hit on 3+ so roughly 10 or so hits.
With halberds they wound our paper thin "elite" soldiers on 2+ causing 9 wounds and 9 casualties.
Lets assume we also deploy in 6x7, meaning we get 2 ranks of attacks, adding up to a whopping 10 attacks.
WS3 vs WS5 + mark of nurgle (-1 to hit) means our trained soldiers hit on 5+ causing a massive 3 hits. With our amazing S4 we wound on 4+, which means 1,5 wounds, so lets assume that scores a wound. The warriors still get a 5+ armour save, so a 32% chance not to suffer ANY damage. This means empire loses by 9 to start off with, still have 3 ranks, so empire only loses by 6, if warriors fail their 5+ save we lose by 5.
So uumm what? 42 (!) halberdiers averagely lose against 13 (!) mark of nurgle, halberd warriors of chaos. No wonder nobody brings empire infantry... Not sure if any of the math is accurate, but I think its pretty close.
About the pigeons. So you have a 5+ chance to cause a small template S4, AP. Not very convincing.
The more math I do about empire, the more sure I become I chose the absolute worst and hardest army ever. Elves and any kind of demons offer free wins, whenever I play against my local WoC player he just charges everything towards me and I lose, doesn't matter whether my knights charge or not, trolls and daemon princes won't care, I'm lucky if I manage to hit the lords or even hurt the 4+ regen trolls.
I'm utterly lost, I really need help with how to play this army.
Edit: hastily posted, added more.
I stopped reading when you said halberds would be 6x7. Who the hell deploys 42 halberds that way? If your not going horde with them you bring spearmen. Let's try your example with horde halberds with hurricanum support cuz let's face it you don't field halberds without hurricanum. And don't give me crap about adding stuff in - warhamer isn't about throwing one unit against another unit without support. If the warriors had a typical support unit fielded with warriors I would say fine. Anyways here is more realistic math hammer :
18 warrior attacks hit on 3 - 12 hits wound on 2s - 10 wounds
25 halberds swing back hit on 4s - 12.5 hits wound on 4s - 6.25 wounds. Warriors make 2 saves so 4 wounds taken Halberds have 3 ranks so lose but steadfast.
Warriors have 9 guys left, halberds have 32 left.
Round 2.
16 attacks from warriors do 8.89 wounds round it to 9
Halberds 20 attacks do 3.33 wounds. Warriors save 1 so 2 more wounds. Your a smart general so you reform the halberds out of horde going 8 wide now.
7 warriors left vs 23 halberds
14 attacks from warriors do 7.78 wounds round it to 8
16 attacks back does 4 wounds 1 saved so 3 wounds on warriors.
4 warriors left vs 15 halberds
9 attacks from warriors does 5 wounds
10 halberd attacks do 2.5 wounds round to 3 warriors save 1 net 2 wounds on warriors. Halberds still steadfast.
2 warriors left vs 10 halberds.
5 attacks from warriors does 2.78 wounds round to 3
7 attacks back does 1.75 wounds - warriors save .58 so 1 wound net.
1 warrior left vs 7 halberds.
3 attacks does 1.67 wounds round to 2
5 attacks back does 1.25 wounds warriors save .42 so round to 1 wound
Halberds win with 5 dudes remaining.
