Yes. I know how to make them a bit more useful on the battlefield! As long as they experience their rareness, region restrictions and whatnot, elephants work out pretty well with getting decimated by Javelins when you set their secondary attack's charge to about 55, and I usually up it by 5 for each unit to max a of of 65 when you get the the bodyguard, then add the attributes of ap, bp, area, and launching, for maximum affect and damage. Elephants really become useful..er after that. Just an FYI.
