JHI are no problem at all, they tire fast and beefed up Militia sergs (about the same price) take them down without too much problems...CFK same story. Camels, well you have to keep your cav away from them at all cost or your battle will be lost.

I perceive camels as being the best units in the game, not per se cause they are so strong,fast or whatever, but because they are the deciding factor in my 'perfect' army (nearly never lost with it in dozens&dozens of online games). Because I have camels, the enemy's cav is nearly useless unless very well employed. Hence I don't need to rely on my own cav to take his out.
