Suppose the top tier elephant units run amok too. This would be realistic (after all, as with men, even well-trained elephants are not entirely immune to fear). Of course, this would place the Indian generals and bodyguards into an even more precarious position. I believe a remedy for such a problem would be to change to the Indian factions to have horse-mounted generals and bodyguards. This would not only improve the mobility and general ease-of-use for these generals, but it might also be more realistic; Rajput warlords, after all, valued horsemanship and would likely proudly demonstrate their prowess as horsemen in battle instead of risking their lives atop a much less reliable animal.
