The discussion oftentimes is one sided. I'll admit my bias, however I am doing the best I can to remain reasonable and rational on the discussion, to stay as close to objectivity as possible, and it is a little bit frustrating to see most "anti-mount" people who oftentimes exaggerate the capabilities of mounted players.Just wanted to point out that there more options then mentioned and the discussion feels sometimes a bit... one sided.
But I fully agree with what chingaperros said above.
There were plenty of issues with terrain negotiation, and that mostly just stemmed from SV not having any clear way of cleaning up their terrain and map. Netcode and networking was just bad all the way around which exaggerated the issues presented by mounts.
I think it's double important to note though that many videos providing examples of "mounts OP" oftentimes show the infantry group having done multiple things wrong, or making themselves ineffective at countering them. Closing up your spacing, keeping a mage on retainer or two, cheap bows with arrows you can still use without skills to do damage to a mount. All these things and more, and people just don't want to listen.
