Just to get an other datapoint: we used to build tests for selenium with selenium ide too, but quickly found out that the used selectors for the elements often had to be manually tweaked, and so we switched to http://nightwatchjs.org/ for our tests, and write them by hand.

Tests are more reliable now, and devs are happy with it. Based on my (limited) experience, selenium ide is not something that is absolutely needed. It's a fine piece of software, but devs can do fine without.
