So, I was playing today, riding about on my dear ol' Dracolisk, and thoughts happened? For better or worse. Or insignifigance. xD
Anywho, personally, I think a good (and hopefully simple enough?) way mounts could be further improved would be to incoperate them into the game more than they currently are. Perhaps this could even be done in DA:I via future DLC installments? Hum. Doubtful, of course, but! XD
A good example would be.... hum. A cutscene that starts with or shows the Inquisitor riding into a location, utilizing whatever mount they had, ah. Equipped? at the time. Having your horse/dracolisk/hart/nuggalope o' epicness show up in a more cinematic sense, even if just breifly, would be a nice personal touch to your experience as the player, and take advantage of this feature they've fashioned for us a bit more creatively, perhaps.
A more involved option could be some sort of chase sequence or something along those lines involving actual gameplay, such as if the Quizzy had to escape via their mount. That'd be fairly simple a concept, just your typical run, avoid objects, and try not to get caught kind of deal. It'd be similiar to the racing sidequest in that it would bring the mounts to your attention again, and incorporate them into legit gameplay. Plus, it'd give the dev team an opportunity to mix things up for a bit gameplay wise.
Eh! XD
