Well, I am similar in that I don't chain them either, so it probably won't affect my play style. I don't think I've ever had more than one copy of the same emergency power skill in my power tray. It also seems to be more of an issue for pvp where the opponents are live humans. I haven't pvp'd in forever, though I can see my self doing some if they do a pvp reputation.
I do think that these changes may help cruiser dps, though, because of the improvement to emergency power to weapons.
