The Elder Scrolls Online "Ask Us Anything": Character Creation

Many of the questions submitted by the community have been focused around character creation since ZeniMax and Bethesda released their walkthrough video, so it comes as no surprise that the latest "Ask Us Anything" feature seeks to address a good portion of them. Here we go:
As the constantly changing person as I am, I tend to always want to change hairstyles on my characters in-game after a little while to make it match a certain armor, or the likes. So, my question is: will it be possible to change your hairstyle or other appearances (like tattoos) in-game after you have created your character? - Therese Ström

For the initial release of the game, you'll only be able to select hairstyle and adornment choices in the character creation screen at the beginning of the game. We hope to provide enough options to allow you to create a unique avatar. But we feel the same as you over time, players want to change their appearance as they develop their characters, so we do have plans to release additional hairstyles, tattoos, adornments, etc. in post-launch content updates.

All weapons can be used to block. What is the advantage of using a shield? Do I have to be in combat mode for my shield to be blocking? - Burwell Thompson, III

Shields have larger amounts of armor and have more mitigation when blocking than weapons do. They're also used in the one-hand and shield skill line. For abilities in that skill line to function, you need to have a shield equipped.

Can you tell us a bit more about the resurrection or reappearance of characters who die in PvP? - Roger Kress

When you die in PvP, there are several options that allow you to rejoin the battle. An ally can resurrect you if they have a filled soul gem, you can respawn at a keep your alliance owns (as long as it isn't under attack), or you can respawn at your alliance's entry location to Cyrodiil. Also note that a siege weapon called a (forward camp) can be deployed this allows a limited number of respawns for your alliance. If one of these forward camps is available, it will be visible as an option when you choose your respawn location. Forward camps are costly and can only be deployed far away from other camps from your alliance.
