I saw pictures on another post where a toon was riding two different horses that are currently in the game.
I really like this idea, from the general statement of what you said. I see how pets would be useful, they could add you buffs as timers such as status bonuses (strenght, dexterity, focus, and/or vitality). Another thread on the Feedbacks and Suggestions section has been posted the same, but highly more detailed description of the post you have posted about the pets; no minions. To me, suggestion would be that pets give status buff(s) and the minions be attack mobs for all classes, but recommended for druids or rangers. They may not act independently, the user has to press auto attack on a mob. I suggest for either one of them to have regeneration for either energy or health.
The reason i quoted you is because i actually saw this certain person's post. If you're not joking at all, i may have to tell you that you are gullible, no offense intended. He just used "jump" at the right place at the center of the horse(s). The first horse is called "Connacht Warhorse - Level 50" (6 mobs in total) it is located near greygorge's camp area and shalemont river with two specific locations, near severen skystrike's spawn (where the screenshot was taken) and near redbane's spawn to the left (in his perspective, facing him in your perspective would be to your right). The second screenshot was located near highshore village. That mob is called "Nightmare - Level 9" (2 mobs in total). It so happens to be located near the road from crossroads leystone, and on towards the [right] side area from highshore village, in respective to crossroads leystone. There is also another Nightmare located near the road going to StoneFang spawn.
I do not, nor intend to hurt or degrade anyone, just creative criticism as it may.
