I have watched a few videos but trying to not pay to much attention as I will likely give it a try but I understand your caution. One thing I haven't heard any one talk about is add-ons. If you look at ESO add-on using LUA script really change how that game plays. The elite running the four person content won't even group unless someone has certain add-ons enabled. With add-ons a solo player can accomplish much of the content designed for a four person group as they allow you to maximize how you heal, your burst DPS and damage mitigation. It will be interesting to see if they address the issue or just ignore it entirely.
