I would agree with removing the egis, but only if the remaining temporary summons become the overwhelming focus of the class at all levels that you would have had a pet. Summoning big, powerful things that come in quick and leave after a time, only to be replaced by another one.

The Egis, if kept, should be an oGCD you use at some point to temp summon more summons or what have you, but existing simply as a permanent DoT isn't very interesting by itself.
