I know there are several threads on chat functions for consoles, but they all seem to be for/against threads. Putting that aside and just thinking about the functionality, while I think it will mostly be fine to not have text chat there are a few areas that I wonder how to approach on consoles without text. Some are unique to ESO.
1) How to buy stuff from players? I have found in many cases the best way to buy/sell things in ESO is WTB/WTS in zone chat. The guild stores (that I have looked at) seem extremely overpriced and its actually quite a complex system compared to standard auction houses, making buying/selling already inherently more difficult than in other mmos. Selling/buying services (vampire bites etc) is even more difficult because there is no game system for that other than text chat.
2) Grouping for dungeons? Does the LFG tool even work? Every dungeon I have run is either with friends or typing LFG in zone chat.
3) PvP grouping? Is there even a grouping tool in pvp? No text chat could work fine if there was a smart group tool for PvP like in Warhammer online, but how do we do it without text in ESO?
Well that's three areas I use chat for a lot and am unsure how to replace without text chat. Please let me know if you have solutions, or if there are other areas that will make things functionally difficult in game without text chat.
