So a couple things on the pvp stuff.

1. I think the system ESO has now is pretty unique and fun, however most can agree that there can be some improvements.
-When you are in a group it would be nice if the leader could have a set of commands that would pop up in white bold print above the health bar for the rest of the players. This would make it a lot easier to work as a group, because you don't have to constantly squint at the comment bar while in combat.
-Also have the opportunity for group leaders to communicate with other group leaders, so multiple groups can strategize across the map. (Im pretty sure you can do this already, but the simpler the system the better.)

2. Horse Combat. We all want to be able to fight on horseback, which was available in Skyrim. My guess from the pictures above that horse combat will be issued next update, but here are some suggestions on what I think would be really cool.
-Horse Armor and weapons. It would be so awesome if you could outfit your horse with dope armor, obviously have to make the horse's stamina go down but it could take more damage. Also having weapons specifically for horse combat would be so fun. For example, lances, bow, and sabers; swords designed for mounted combat.
-Your horse should be able to die. It is really sad, but more realistic. I know how much a horse costs and I think if your horse dies, you could summon it again once you have left combat. Having your horse die and being able to fight on horse back would add a lot to game, and game strategy.

Feel free to comment and share your thoughts.
