I've played Archons with Life enough times to realise that Avengers without bolts totally suck when compared to Crusaders. Pathetic defense, average hp and mp...whats the use of three different strikes with ew when you can get your head handed to you easily? Charioteers are the staple...better defense, hp, ranged attack and only slightly costlier. You are talking about comparisons - get 8 Avengers vs 8 Bruisers and test it. And Archons, gold penalty and war shrine? A nice idea...
And Archons need Order Shrine for their high-cost units or Nature Shrine to alleviate the gold penalty and increase growth for hurrying. Stranger, you are probably a more frequent player of Archons than me, how many times have you built a War Shrine in your cap?
Now, to the crusader. The current crusader is nothing but an average-in-all-stats melee and expensive to boot! Wildblade - probably the most fearsome infantry in the whole game and he costs less than Crusader (Throw blade with 7 att is far more powerful and effective than throw spear). Bruiser - again high attack and charge, cheaper. They were one of the better infantry - at silver, they can chew through toughies too with their charge. Undead - death strike, resurgence, cheaper. Barbarians - Stranger already listed their advantages. Humans - low cost, similar stats, absence of holy strike and so on. Where was the reasoning to remove Holy Champ from the Crusader? You remember it was done once before and it had a disastrous result in the actual testing?
And if you recall the discussion we had many a night ago about Archons - they suffer terribly in a long game, and all those who say 'no' should try them out before posting it. Which was one of the reasons a small research bonus was given to them - and now more nerfs? We also discussed a ranged bolt attacker (bolt attack at start) for the Archons atleast in the Sanctum - something like atleast what the Brethren Mage was. Which I took to assume - Archons needed a little more boost, and now a nerf?
And all this talk of evil units needing a boost - they are as good as it gets now. Goblins - incredible growth and dirt cheap units, Undead - research bonus and decent units with lower levels sustainable in numbers with healing, Orcs - powerful and normal growth, Demons - good bonus and decent units, Dark Elves - cool and effective units to lend a vast variety of options.
All the evil races match up well with the good races except against Archons and here too, they don't fare that badly. And Archons have a gold penalty (this hurts very bad in the long run and in the initial phase when everyone can hurry an infantry now and then) and all units have a pretty high cost. Sounds like a good enough balance to me.
Just like people asking for unit boosts do so after playing with them, ppl should also play with the units they are asking to nerf before asking...playing against them can tilt your view any which way. Yes, your 16 goblin swordsmen lost against a bunch of crusaders - but what was the cost and effort to field your 16 swordsmen compared to the bunch of crusaders? And how soon can you do it again? Play Archons and you lose a major battle - you are screwed a little more than when playing any other race coz the cost of rebuilding an army is way higher for Archons than other races.
You want stats? Let me give you some, from the excel file itself.
The average (average is without lvl4 and temple units and machines, btw) Archon cost is 131 - which is almost 20 higher than the highest Evil race cost (Undead) and nearly 40 more than the second highest Evil race cost (Demons) and more than 15 compared to the next highest cost among all races. Average attack higher than the Demons (I'll ignore the DE becoz their units have different kinds of strikes - poison, death, cold, lightning and cool abilities) and average defense equal to most (again, I can ignore the Gobbos because of their dirt cheap cost). So, in a game where all here are discussing only about combat, the average Archon soldier costs much more to field and has not much difference when compared to att and def...statistically. Individual comparisons can be done, but as a whole, the game offers enough alternatives that the bigger picture is more balanced between good and evil - just get that Holy Champ back! 
I think I can rant on for another couple of paragraphs but let me stop here....
