Adsl (not much performing I have to say, often as bad as dial-up) and cables existed (along with other tecnologies you never heard about) already and even ISDN could bring you down to 45-50 ping if the shard was located in the same continent, I could say not much changed for Uo players since then. having a decent ping in another continent it's STILL an issue.
I have no idea what's your ping or how is your connection but everyone knows that mounts put you on a disavantage if your ping is above 150 (maybe even 120), which is more or less what euro players ping here at their best, (Asians and Australians/Neo Zeeland players even worse).
It's well know if your ping is hight you operate better on foot this is the reason why Ipy have no mounts on first place.
I 'm sorry you were not aware of all this.
